Webwhere A1 = D 1 2 /4 (pipe cross-sectional area), = d/D 1 (ratio of orifice to pipe diameter), C d = discharge coefficient, and Y = compressibility factor. The discharge coefficient is a function of the Reynolds number and the diameter ratio and is the ratio of actual discharge to the theoretical discharge.
WebJul 24, 2024 · 1. I would like to understand how to calculate the Reynolds number in the test chamber of a wind tunnel. It is known that the Reynolds number for a pipe is: R e = U L ν. where. U is the fluid velocity. L is the characteristic length (usually the diameter of the pipe). ν is the kinematic viscosity. WebThe Reynolds number is a dimensionless number. High values of the parameter (on the order of 10 million) indicate that viscous forces are small and the flow is essentially inviscid. The Euler equations can then be …
