Reyn Ouwehand
In fluid dynamics, the reyn is a British unit of dynamic viscosity, named in honour of Osbourne Reynolds, for whom the Reynolds number is also named.Juvinal, Robert C. & Marshek, Kurt M.; ''Fundamentals of machine component design''. 2nd ed., 1991, pp. 480, Conversions By definition, :1 reyn = 1 lbf s in−2. It follows that the relation between the reyn and the poise is approximately :1 reyn = 6.89476 × 104 P. In SI units, viscosity is expressed in newton-seconds per square meter, or equivalently in pascal Pascal, Pascal's or PASCAL may refer to: People and fictional characters * Pascal (given name), including a list of people with the name * Pascal (surname), including a list of people and fictional characters with the name ** Blaise Pascal, Fren ...-seconds. The conversion factor between the two is approximately :1 reyn = 6890 Pa s. References External links ReynHistory of the unit Fluid dynamics Units of dynamic viscosity {{Fluiddynamics-stub ...

Fluid Dynamics
In physics and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids— liquids and gases. It has several subdisciplines, including ''aerodynamics'' (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation. Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves the calculation of various properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space and time. ...
