Saturated steam at 110C is condensed in a shell-andtube
Chapter , Problem 11.42(choose chapter or problem)
Saturated steam at 110C is condensed in a shell-andtube heat exchanger (1 shell pass; 2, 4, ... tube passes) with a UA value of 2.5 kW/K. Cooling water enters at 40C. (a) Calculate the cooling water flow rate required to maintain a heat rate of 150 kW. (b) Assuming that UA is independent of flow rate, calculate and plot the water flow rate required to provide heat rates over the range from 130 to 160 kW. Comment on the validity of your assumption
