Computing reynolds number
WebCalculator description. Reynolds number named after Osborne Reynolds (1842 – 1912), gives the relation between inertial and viscous forces of fluid flow. If inertial forces (flow rate) are much bigger, and Reynolds number is higher than critical, Re > 2320, fluid flow is turbulent, and if viscous forces are big enough in comparison to ...

WebReynolds Number Example Problems. Problem 1- Calculate Reynolds number, if a fluid having viscosity of 0.4 Ns/m 2 and relative density of 900 Kg/m 3 through a pipe of 20 mm with a velocity of 2.5 m. Solution 1 – … Reynolds numbers are used in airfoil design to (among other things) manage "scale effect" when computing/comparing characteristics (a tiny wing, scaled to be huge, will perform differently). Fluid dynamicists define the chord Reynolds number R = Vc/ν, where V is the flight speed, c is the chord length, and ν is the kinematic viscosity of the fluid in which the airfoil operates, which is 1.460×10 m /s for the atmosphere at sea level. In some special studies a characteristic length ot…
