Webb8 juni 2015 · Flow coefficients. The flow coefficient for liquids, CV, is determined experimentally for each valve or fitting as the flow of water, in gal/min at 60°F for a pressure drop of 1 psi through the fitting. The relationship between flow and resistance coefficients can be expressed as. (Eq. WebbPressure drop along a pipe is dependent on several factors and may be calculated using the equation below: Δ P = f L D ρ v 2 2 Where: P is the pressure drop. f is the friction … Away from the ends of the pipe, the characteristics of the flow are independent of the position along the pipe. The key quantities are then the pressure drop along the pipe per unit length, Δp/L, and the volumetric flow rate. The flow rate can be converted to a mean flow velocity V by dividing by the wetted area of the flow (which equals the cross-sectional area of the pipe if the pipe is full of fluid). city of godley municipal court
