Chemical Engineering Thermodynamics - Humidity

A cooling water stream leaves the condenser in the formalin 37/3 process at a temperature of 45C and a flowrate of 12 kg/s. It is sent to a cooling tower to be cooled down to 16C for reuse. The worm cooling water is sprayed down from the top of cooling tower. Ambien air is blowed into the cooling tower from the bottom and going up to directly contact with the warm cooling water. The cooling tower is operated adiabatically. It is allocated in Birmingham in the UK. Calculate: 1. The typical minimum air flowrate required to achieve the cooling if the air reached saturations when it leaves the cooling tower in different seasons. 2. The air flowrate required to achieve the cooling if the air has a relative humidity of 80% when it leaves the cooling tower in different seasons. (4 marks) If the air flow is fixed at a flowrate as calculated from above (2), calculate 3. the temperature of the cooling water that leaves the cooling tower from the bottom at different time in a selected day. Present your calculation results in a diagram 4. the water-loss amount at different time in the selected day. Present your calculation results in a diagram. (8 marks) Comments on your calculation results from 3 and 4 above in terms of 1) how to achieve steady-state operation; 2) the values from site measurements
