Solving for power dissipated.

power dissipated

Inputs:

air flow rate at atmospheric pressure (Qa
discharge point air pressure (h) 


Conversions:

air flow rate at atmospheric pressure (Qa) = 0    = 0  foot^3/minute
discharge point air pressure (h) = 0    = 0  foot of water


Solution:

power dissipated (P)  =  HAS NOT BEEN CALCULATED
