Flow coefficient vs reynolds number
WebThe discharge coefficient is the actual flow ratio with the theoretical flow and makes allowances for flow contractions and friction effects. The discharge coefficient is a … WebThe friction factor is part of a more comprehensive drag coefficient, which can be used to calculate the total drag based on fluid velocity and the cross-sectional geometry of the moving object. As we’ll see, the friction factor depends on the Reynolds number and the fluid flow regime (laminar vs. turbulent flow). However, the friction factor ...
