WebFriction Loss in Fittings Valves As an aid, liquid sizing constants (Cv values) are shown for valves. These values are defined as the flow rate through the valve required to produce a pressure drop of 1 psi. To determine the pres-sure drop for a given GPM the following formula may be used. ∆P = (G2)(SG)/Cv2 where: AP = pressure drop G= Flow ... WebMay 26, 2016 · In general, the loss on a fitting is the velocity pressure multiplied by the loss coefficient. This can be confirmed in the pressure loss report: For the “4x greater” case of the custom tee, we tried to reproduce and were unable to do so. immigration advice newham
