A cooling tower of a centralized air conditioning system handles 5,000 m³/h of water which enters the tower at 40°C. The cooled water leaves the tower at 28°C. The drift loss is 0.1% while the blowdown is 0.4%. The water make-up is 150 m³/h at 30°C. The air blown through the tower enters at 25°C and has a relative humidity of 70%. The air leaves the tower at 35°C with a relative humidity of 95%. Calculate the volume of air, in m³/h at ambient conditions that the forced draft fan of the cooling tower handles.

Question
A cooling tower of a centralized air conditioning system handles 5,000 m³/h of water which enters
the tower at 40°C. The cooled water leaves the tower at 28°C. The drift loss is 0.1% while the
blowdown is 0.4%. The water make-up is 150 m³/h at 30°C. The air blown through the tower
enters at 25°C and has a relative humidity of 70%. The air leaves the tower at 35°C with a relative
humidity of 95%. Calculate the volume of air, in m³/h at ambient conditions that the forced draft
fan of the cooling tower handles.
