Note:
1.CFM = Cubic feet per minute
2.TMBH = Total capacity (MBH)
3.GPM = Gallons per minute
4.WPD = Water pressure drop (feet of water)
5.Q/ITD = MBH (kW)/(Entering water temperature - Entering air temperature) when DT and GPM (L/s) remain constant. To determine heating capacities at a different entering water temperature or entering air temp, compute the new ITD and multiply it by the Q/ITD shown.
6.Medium and low speed capacities are approximately 80 percent and 60 percent respectively of the high speed capacity.
7.High static motors need the appropriate length of duct to prevent poor acoustical applications.
