Common Formulas
| Face Area (ft2): | FA = FH x FL / 144 |
| Face Velocity (fpm): | FV = SQEM / FA |
| Heating Applications: | SH = 1.085 x SCFM x (DBL – DBE) GPM = SH / 500 x (EWT – LWT) |
| Cooling Applications: | TH = 4.5 X SCFM X (HE – HL) SH = 1.085 x SCFM x (DBE – DBL) GPM = TH / 500 X (LWT – EWT) |
| Where: | DBE = Entering air dry bulb (°F.) DBL = Leaving air dry bulb (°F.) EWT = Entering water temperature (°F.) FA = Coil face area (ft2) FH = Finned height (in.) FL = Finned length (in.) FPM = Feet/minute FV = Face velocity (fpm) | GPM = U.S. gallons/minute of water HE = Enthalpy of entering air (BTU/lb.) HL =Enthalpy of leaving air (BTU/lb.) LWT = Leaving water temperature (°F.) SCFM = Standard cubic feet/minute of air SH = Sensible heat (BTU/hour) Total heat (BTU/hour) |
