Notes :
1. Coils air pressure drop is included in static pressure
requirement charts.
2. Coils are leak tested at 300 psig air pressure under
water.
3. Capacities based on 180 degrees entering water
temperature, 55 degrees entering air temperature, and 0.00025 fouling factor. See capacity
correction factors for different entering temperatures.
4. The following equations may be used in calculating
Leaving Air Temperature (LAT) and Water Temperature Difference (WTD) :
LAT = EAT + (MBH x 921.7 / CFM)
WTD = EWT - LWT = (MBH x 2.04 /GPM)

Note :
1. Multiply water pressure drop from Hot Water Coil Capacity
Table by correction factor to get water pressure drop at various entering water
temperature.
