2. Conversion — Bhp to watts:
Bhp — Brake Horsepower edb — Entering Dry Bulb
Watts =
Bhp x 746
ewb — Entering Wet Bulb
NOTES:
1.Fan performance is based on wet coils, economizer, roof curb, cabinet losses, and clean
Motor efficiency
3.Variable air volume units will operate down to 70 cfm/ton. Performance at 70 cfm/ton is limited to unloaded operation and may be additionally limited by edb and ewb conditions.
