WebCONVERSION CHART Velocity Pressure (IN. W.C.) to Velocity (FPM) CALCULATIONS The Pitot tube is the primary standard used to calibrate all other air-flow measuring … WebLet’s put it to use Case 1 We need to heat up an air flow of 25 CFM at a pressure of 30 psig, and 90°F up to 200°F. Convert flow to SCFM: 30 psig = 44.7 psia, 90°F = 550°R SCFM = (25)* (44.7/14.7)* (528/550) = 73 SCFM The equation Q/t = (m/t)*cp*ΔT can be approximated for air to: Power [Watts] = (1/3)*SCFM*ΔT [°F]

WebThe following formula can be used to convert the actual flow rate to standard flow rate, in cubic feet per minute. The flow rate in other units can be determined by converting them into cubic feet per minute before and after using the formula. Where: T = Gas temperature (°F) P = Gas pressure (psia) ACFM = Gas flow (actual cubic feet/minute) WebThe conversion from SCFM to ACFM can be expressed. ACFM = SCFM [P std / (P act - P sat Φ)](T act / T std) (1) where. ACFM = Actual Cubic Feet per Minute. SCFM = Standard Cubic Feet per Minute. P std = standard … new era group llc
