Inlet temperature of the cooling water (T_C,i) = 16 C

Oil mass flowrate (_h) = 100kg/s

i) All equation(s) or figure(s) used must be from the textbook. ii) You must indicate the number(s) of equation(s) or figures(s) used in your calculations. Design a shell-and-tube heat exchanger with one shell pass and eight tube passes. The heat exchanger is required to cool mhkg/s of a petroleum oil inside the tubes from 135C to 50C. Water is supplied to the shell at mckg/s and enters at Tc,i. The exchanger should have 200 tubes. The overall heat transfer coefficient is estimated to be 172W/m2K. For the oil, take Cp,h=2200J/kgK and for the water, take Cp,c=4180J/kgK. Neglect heat loss to surroundings, (i) determine the required heat exchanger areas for three water mass flowrates, mc,160kg/s,170kg/s and 180kg/s, respectively, (ii) based on your results, discuss the effect of water flowrate on the required surface area of the heat exchanger
