A 1-2 shell and tube heat exchanger have cold water flowing inside the pipes and while hot fluid flows on the outside across the tubes. The flow rate of the hot fluid is 115 kg/s, and they are cooled from 330 C to 200 C, has the specific heat of 1075 J/kg.K. The cold water enters at 25 C with a flow rate of 700 kg/s. The overall heat transfer coefficient is determined at 23.5 W/mK, density and specific heat of the cold water is 1000 kg/m and 4187 J/kg K, respectively. Assuming a counter flow heat exchanger, (a) (b) Calculate the outlet temperature of the cold water and the area required for heat transfer. [13 Marks] [CO1, PO1, C4] Determine the maximum heat transfer rate and the effectiveness of the heat exchanger.
