    FYI, friction losses for a 100 ft. length of 6" diameter PVC pipe are figured at 0.30 psi / 100 ft. of pipe. The friction loss data is different for different pipe materials, and is IMO always wrong for in-use systems where contaminants or Chinage have changed the surface properties of the piping to increase (roughing or wear or mineral deposits) or decrease (algae) friction losses.

    Flow Rate Calculator - Good Calculators

    The rate at which a liquid flows will vary according to area of the pipe or channel through which it is passing and the velocity of the liquid. Units that are commonly used to measure volumetric flow rate are: m 3 /s (cubic meter per second), L/min (liters per minute), ft 3 /sec (cubic feet per second), ft 3 /min (cubic feet per minute, or CFM), and gal/min (gallons per minute, or GPM).
