WebNov 11, 2003 · Use 300-450 pa/m. 1-4 ft friction loss per 100 ft of pipe; 2.5 ft as mean. For noise, keep velocity less than 4 feet per second (fps) for 2" dia. and smaller pipes. For greater than 2" dia., keep PD <4 ft per 100 ft pipe. If you reduce air and turbulence, you can exceed the 4 ft limit. Web6.7 PUMP SPEED. The pump speeds available for chilled water pumps include 1,200, 1,800 and 3,600 RPM. When you choose the pump speed, you must first ensure that the pump manufacturer has that speed available. Lower pump speeds are preferred because the increased number of rotations will cause increased wear and tear.
