WebJun 30, 2014 · That is 60psi friction loss per 100ft. We have a 200ft line so 60 plus 60 is 120psi total friction loss. Then add your nozzle pressure, 120 plus 100 equals 220psi. 60psi + 60psi + 100psi = 220psi That is your pump discharge pressure. The exact pump discharge pressure for this scenario would be 224.

The “c” term is the so-called friction loss factor and measures the pressure loss per 100 feet. This is multiplied by the square of the volume flow (gpm) and hose length (L) to get total friction loss. The “c” factor is a handy way of comparing results from different tests and flow rates. godfather movie cast teluguWebDarcy-Weisbach equation: hf = f (L/D) x (v^2/2g) where: hf = head loss (m) f = friction factor L = length of pipe work (m) d = inner diameter of pipe work (m) v = velocity of fluid (m/s) g = acceleration due to gravity (m/s²) or: hf = head loss (ft) f = friction factor L = length of pipe work (ft) d = inner diameter of pipe work (ft) bonus plata tebcaWebMar 20, 2024 · Friction Losses.
