Answer:
w ( mass flow rate of air ) = 3.16 kg/s
Explanation:
<u>Determine the mass flow rate of air </u>
mass flow rate of water = 1.5 kg/s
Height at which air enters the cooling tower = 1m
velocity of air entering at 1 m = 20 m/s
Height at which air leaves the cooling tower = 7 m
attached below is a detailed solution of the problem
