AP4+ Bottom inlet, Long Autopump Download PDF Pump Flow Metric Conversion Factors Use these factors to convert from English to metric Data Input For Pump depth and Header back pressure, multiply meters by a factor of 3.33 to input data in units of feet. Flow Rate Multiply U.S. gallons by 3.79 to convert to liters. Air Consumption Multiply SCFM by 0.029 to express in cubic meters. Data Input (feet) Enter pump depth in well Header back pressure Total developed head Flow Rate (gpm) Maximum Enter desired flow rate Default is maximum flow rate Air consumption per pump scfm delivered at 100 psi Number of pumps driven by compressor Total Air Consumption - All Pumps (scfm delivered at 100 psi) Total Compressor Design Specifications (scfm delivered at 100 psi) Rotar/Screw Compressor Reciprocating Compressor Without Dryer 0 0 With Dryer 0 0 See more information for: desiccant dryer, rotary screw and reciprocating compressors. Calculator assumes 10' pump submergence @ 100 psi. Call QED for less than 10' pump submergence. Markets & Applications Help and Support About Terms and Conditions Contact Us Region
