Single Heat Exchanger

Problem Statement

Hot water at 250 °F and 1000 psig is used to heat a cold stream of water in a shell and tube heat exchanger. The inlet temperature and pressure of the cold stream is 125 °F and 130 psig, respectively. The outlet temperature of the cold and hot streams are 150 °F and 195 °F, respectively. If the flow rate of the hot stream is 100 lb/hr, determine the flow rate of the cold stream passing through the exchanger.
