QUESTION #1- HEAT EXCANGER DESIGN Design an exchanger to sub-cool methanol vapours from 95 "C to 40°c. The flowrate of methanol is 20200kg/hr. Brackish water or municipality water or river wvater or treated water can be used as the coolant with a temperature rise from 25 to 4aorc. Heat capacities of methanol and water are 2.84k/kg and 4.2 k/kgC respectively. The densities of methanol and water are 792 kg/m' and kg/m'respectively. Note: po the calculations step by step. Write formulas used in calculations in full along the calculations State all your assumptions You are free to select data from table and charts as youu need it but state reasons for the selection your choices
