	LEGEND	2. The following formulas may be used:
BF	— Bypass Factor	tldb	=	tedb	–	sensible capacity (Btuh)
Edb	— Entering Dry Bulb					1.10 x cfm
Ewb	— Entering Wet Bulb	tlwb	= Wet-bulb temperature corresponding to enthalpy of air
kW	— Compressor Motor Power Input
SHC — Sensible Heat Capacity (1000 Btuh) Gross				leaving evaporator coil (hlwb)
TC	— Total Capacity (1000 Btuh) Gross	hlwb	=	hewb	–	total capacity (Btuh)
*Negative SHC value indicates that the air entering the coil is being						4.5 x cfm

heated.	Where: hewb = Enthalpy of air entering evaporator coil.
NOTES:

	rator coil.
	Below 80 F edb, subtract (corr factor x cfm) from SHC.
	Above 80 F edb, add (corr factor x cfm) to SHC.
	Correction Factor = 1.10 x (1 – BF) x (edb – 80).
