Friction factor for turbulent flow formula

WebThe Moody friction factor, f, is an integral part of the general gas flow equation. Because it is a highly nonlinear function, it must be either read from a chart or determined … WebEquation 2.19 has the advantages of giving f explicitly and being adequately accurate over the whole range of turbulent flow. Use of the friction factor chart or a correlation such as equation 2.19 enables calculation of the frictional pressure drop for a specified flow rate from equation 2.13.
