Friction loss in PVC fittings in equivalent feet of straight pipe This chart gives friction losses for your given flow rate per 100 feet of pipe. Example: If you have 3600 gallons per hour and you're using 2 inch schedule 40 pipe and you have a 160 feet of pipe, your friction loss is 5.84 x 1.6 = 9.34 feet. Note: It is best to keep your friction loss (per 100 feet of pipe) to less than five feet. |
