Notes :
1. Coils air pressure drop is included in static pressure
requirement charts.
2. Coils are leak tested at 31.3 kPa air pressure under
water.
3. Capacities based on 82.2º C entering air
temperature, 12.8º C 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 + (KW x 824.6 / Airflow L/s)
WTD = EWT - LWT = (MBH x .244 /L/s)

Table by correction factor to get water pressure drop at various entering air and water
temperatures.
