RMS Viceroy Of India
RMS ''Viceroy of India'' was an ocean liner of the Peninsular and Oriental Steam Navigation Company (P&O). She was a British Royal Mail Ship on the Port of Tilbury, Tilbury–Mumbai Harbour, Bombay route and was named after the Viceroy of India. In World War II, she was converted to and used as a troopship. She was sunk in the Mediterranean in November 1942 by . Building P&O ordered the ship from Alexander Stephen and Sons of Glasgow in 1927. She was originally to be called ''Taj Mahal'', after the 17th-century mausoleum of Mumtaz Mahal in Agra. She was laid down in April 1927, launched in September 1928 and completed in March 1929. She cost £1,090,987 She had six water-tube boilers with a combined heating surface of that supplied steam at 400 Pounds per square inch, lbf/in2 to two turbo generators. These supplied current to electric motors with a combined rating of 3,565 Horsepower#Nominal horsepower, NHP that drove twin Propeller (marine), screw propellers. British Thomson ...

Governor-General Of India
The Governor-General of India (1773–1950, from 1858 to 1947 the Viceroy and Governor-General of India, commonly shortened to Viceroy of India) was the representative of the monarch of the United Kingdom and after Indian independence in 1947, the representative of the British monarch. The office was created in 1773, with the title of Governor-General of the Presidency of Fort William. The officer had direct control only over Fort William but supervised other East India Company officials in India. Complete authority over all of British territory in the Indian subcontinent was granted in 1833, and the official came to be known as the "Governor-General of India". In 1858, because of the Indian Rebellion the previous year, the territories and assets of the East India Company came under the direct control of the British Crown; as a consequence, the Company rule in India was succeeded by the British Raj. The governor-general (now also the Viceroy) headed the central governmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller (marine)
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the water at t ...

Three-phase Electric Power
Three-phase electric power (abbreviated 3φ) is a common type of alternating current used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power. Three-phase electrical power was developed in the 1880s by multiple people. Three-phase power works by the voltage and currents being 120 degrees out of phase on the three wires. As an AC system it allows the voltages to be easily stepped up using transformers to high voltage for transmission, and back down for distribution, giving high efficiency. A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Three-phase power is mainly used directly to power large induction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rugby, Warwickshire
Rugby is a market town in eastern Warwickshire, England, close to the River Avon. In the 2021 census its population was 78,125, making it the second-largest town in Warwickshire. It is the main settlement within the larger Borough of Rugby which has a population of 114,400 (2021). Rugby is situated on the eastern edge of Warwickshire, near to the borders with Leicestershire and Northamptonshire. Rugby is the most easterly town within the West Midlands region, with the nearby county borders also marking the regional boundary with the East Midlands. It is north of London, east-southeast of Birmingham, east of Coventry, north-west of Northampton, and south-southwest of Leicester. Rugby became a market town in 1255, but remained a small and fairly unimportant town until the 19th century. In 1567 Rugby School was founded as a grammar school for local boys, but by the 18th century it had gained a national reputation as a public school. The school is the birthplace of Rugby foo ...

British Thomson-Houston
British Thomson-Houston (BTH) was a British engineering and heavy industrial company, based at Rugby, Warwickshire, England, and founded as a subsidiary of the General Electric Company (GE) of Schenectady, New York, United States. They were known primarily for their electrical systems and steam turbines. BTH was taken into British ownership and amalgamated with the similar Metropolitan-Vickers company in 1928 to form Associated Electrical Industries (AEI), but the two brand identities were maintained until 1960. The holding company, AEI, later merged with GEC. In the 1960s AEI's apprenticeships were highly thought-of, both by the apprentices themselves and by their future employers, because they gave the participants valuable experience in the design, production and overall industrial management of a very wide range of electrical products. Over a hundred of the apprentices - who came to Rugby from all over the UK, and a few from abroad - lodged in the nearby Apprentices' Host ...

Turbo Generator
A turbo generator is an electric generator connected to the shaft of a steam turbine or gas turbine for the generation of electric power. Large steam-powered turbo generators provide the majority of the world's electricity and are also used by steam-powered turbo-electric ships. Small turbo-generators driven by gas turbines are often used as auxiliary power units (APU, mainly for aircraft). History The first turbo-generators were electric generators powered by water turbines. The first Hungarian water turbine was designed by the engineers of the Ganz Works in 1866; industrial-scale production with dynamo generators started only in 1883. Engineer Charles Algernon Parsons demonstrated a DC steam-powered turbo generator using a dynamo in 1887, and by 1901 had supplied the first large industrial AC turbo generator of megawatt power to a plant in Eberfeld, Germany. Turbo generators were also used on steam locomotives as a power source for coach lighting and water pumps for heat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pounds Per Square Inch
The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 Pa. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pounds per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to something other than ambient atmospheric pressure, then the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water-tube Boilers
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agra
Agra (, ) is a city on the banks of the Yamuna river in the Indian state of Uttar Pradesh, about south-east of the national capital New Delhi and 330 km west of the state capital Lucknow. With a population of roughly 1.6 million, Agra is the fourth-most populous city in Uttar Pradesh and List of cities in India by population, twenty-third most populous city in India. Agra's notable historical period began during Sikandar Lodi's reign, but the golden age of the city began with the Mughals. Agra was the foremost city of the Indian subcontinent and the capital of the Mughal Empire under Mughal emperors Babur, Humayun, Akbar, Jahangir and Shah Jahan. Under Mughal rule, Agra became a centre for learning, arts, commerce, and religion, and saw the construction of the Agra Fort, Sikandra, Agra, Sikandra and Agra's most prized monument, the Taj Mahal, built by Shah Jahan as a mausoleum for his favourite empress. With the decline of the Mughal empire in the late 18th century, the ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mumtaz Mahal
Mumtaz Mahal (/'/; ), born Arjumand Banu Begum (27 April 1593 – 17 June 1631) was the empress consort of the Mughal Empire from 19 January 1628 to 17 June 1631 as the chief consort of the Mughal emperor Shah Jahan. The Taj Mahal in Agra, often cited as one of the Wonders of the World, was commissioned by her husband to act as her tomb. Mumtaz Mahal was born Arjumand Banu Begum in Agra to a family of Persian nobility. She was the daughter of Abu'l-Hasan Asaf Khan, a wealthy Persian noble who held high office in the Mughal Empire, and the niece of Empress Nur Jahan, the chief wife of Emperor Jahangir and the power behind the emperor. She was married at the age of 19 on 10 May 1612 or 16 June 1612 to Prince Khurram, later known by his regnal name Shah Jahan, who conferred upon her the title "Mumtaz Mahal" (Persian: the exalted one of the palace). Although betrothed to Shah Jahan since 1607, she ultimately became his second wife in 1612. Mumtaz and her husband had 14 children, in ...

Mausoleum
A mausoleum is an external free-standing building constructed as a monument enclosing the interment space or burial chamber of a deceased person or people. A mausoleum without the person's remains is called a cenotaph. A mausoleum may be considered a type of tomb, or the tomb may be considered to be within the mausoleum. Overview The word ''mausoleum'' (from Greek μαυσωλείον) derives from the Mausoleum at Halicarnassus (near modern-day Bodrum in Turkey), the grave of King Mausolus, the Persian satrap of Caria, whose large tomb was one of the Seven Wonders of the Ancient World. Historically, mausolea were, and still may be, large and impressive constructions for a deceased leader or other person of importance. However, smaller mausolea soon became popular with the gentry and nobility in many countries. In the Roman Empire, these were often in necropoles or along roadsides: the via Appia Antica retains the ruins of many private mausolea for kilometres outside Rome. Whe ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
