​Air Cooling Equations:
Total Sensible Heat (BTUH)
            Total Latent Heat (BTUH)
            Total Sensible Heat = Total Sensible Heat + Total Latent Heat
            Grand Total Heat = Total Sensible Heat + Total Latent Heat
            Grand Total Heat (BTUH)

Pump Equation:
Pump HP =
Fan Equation:
            Fan HP =

Legend:
            BTU    = British Thermal Unit
BTUH = BTU per Hour
CFM   = Cubic Feet per Minute of Air
EAT    = Entering Air Temperature
LAT    = Leaving Air Temperature
EASH = Entering Air Specific Humidity (Grains per pound of air)
LASH = Leaving Air Specific Humidity (Grains per pound of air)
EAEN = Entering Air Enthalpy (BTU per pound of air)
LAEN = Leaving Air Enthalpy (BTU per pound of air)
ΔT      = Temperature difference between entering and leaving fluid
GPM  = Gallons Per Minute of Fluid
SP      = Static Pressure
HP      = Horsepower
