9. A large warehouse located at an altitude of 1500 m has to be maintained at a DBT of 270C and a relative humidity of 50% using a direct evaporative cooling system. The outdoor conditions are 330C (DBT) and 150C (WBT). The cooling load on the warehouse is 352 kW. A supply fan located in the downstream of the evaporative cooler adds 15 kW of heat. Find the required mass flow rate of air. Assume the process in evaporative cooler to follow a constant WBT.
