7 Water VelocitiesVelocities for water in feet per second at different GPM's and pipe inside diameters can be calculated as follows:Where: V = velocity in feet per secondG = gallons per minuteA = inside cross sectional area in square inchesCAUTION: Flow velocities in excess of feet per second are not recommended for closed-end systems. Contact Spears Technical Services for additional & Design Data FLOW VELOCITY & FRICTION LOSSF riction Loss Through FittingsFriction loss through fittings is expressed in equivalent feet of the same pipe size and schedule for the system flow rate.

Where: f = friction head of feet of water per 100' for the specific pipe size and I.D. C = a constant for internal pipe roughness. 150 is the commonly accepted value for PVC and CPVC pipe. G = flow rate of gallons per minute (U.S. gallons). di = inside diameter of pipe in inches. Nominal Size 1/2 3/4 1 1-1/4 1-1/2 2 2-1/2 3 4 6 8 10 12
