Temperature of air ventilated from pump room???
(OP)
I am trying to figure out the temperature of the air that I am ventilating from a pump room to decide whether it needs to be exhausted to the outdoors. I have (2)20hp pumps, I have done a rule of thumb to figure out the Btuh that these will be giving off and came up with 15026 Btuh. (110 Watts per hp> (110*40=4400 Watts > converted to Btuh = 15026). I am moving 1000 cfm out of the room and intaking the same. The room is approximately 100 sq. ft.

air temp rise = 15026/(1000*1.08)= 13.91 Deg.F
Assuming 95 Deg. Entering air, leaving air = 95 + 13.91 = 108.9 Deg.F
Hope this helps.

The air temperature rise = btu/hr divided by 1.08 x cfm.
If both pumps run continuously, this will be an extremely hot room.

Sounds pretty hot. Is that reasonable?
