NOTES:

1.Direct interpolation is permissible. Do not extrapolate.

2.The following formulas may be used:

sensible capacity (Btuh)

1.10 x cfm

tlwb = Wet--- bulb temperature corresponding to enthalpy of air leaving evaporator coil (hlwb)

total capacity (Btuh)

hlwb = hewb – 4.5 x cfm

Where: hewb = Enthalpy of air entering evaporator coil
