(9720kg/hr) is to be cooled by contact with air in an induced-draft

please answer all.. with the graph

Water from a distillation condenser (9720kg/hr) is to be cooled by contact with air in an induced-draft cooling tower. The design conditions are as follows: Tower operating pressure: 1.013105Pa Entering air: 30C dry bulb with percentage humidity of 60% Entering water: 43C, to be cooled to 29C For the packing to be used, KG a is expected to be 3.06106 kgmol/s.m3.Pa. (a) Calculate Hy1 and determine the minimum air rate that can be used. (b) If the superficial velocity of the air flow is 0.5m/s and the flow rate of air, G=1.75Gmin, estimate the size of the tower in terms of diameter and height. Given: air=1.2kg/m3,cL=4.187103J/kgK Use the given graph in the next page
