You are looking to purchase the DeWalt air compressor. Assumingthe compressor operates (outputs) air at 90psi and at 110F. If theatmospheric pressure is 0 psig and the atmospheric temperature is65F, how much free air will the compressor consume in cubic feet(ft3 )/Minute to handle the 5 standard cubic feet per minute(SCFM)? â€¢ DeWalt Specifications -- 1.6 HP electric engine gets thejob done. High-pressure motor with consistent draw requirements canbe run with a 12-Gauge or higher extension cord that is under 50ft. 200 psi maximum pressure enables long air-tool run timeDelivers 5 SCFM at 90 psi for quick recovery time
