A counter flow cooling tower operates steadily with 100 liter/sec of water that is cooled from 30 C to 25 C. The ambient air is at sea level pressure, 25 C dry bulb and 20 C wet bulb temperature. The ratio of mass flow rate to air flow rate is 1.0.
Determine:
a) the final enthalpy of leaving air and
b) the tower volume is H_dA_v = 0.50 kg/ s*m^3,
Using appropriate method of NTU
