Question:
A condenser is used as a heat exchanger in a large steam power plant in which steam is condensed to liquid water. The condenser is a shell and tube heat exchanger which consists of 1 shell and 20,000 tubes. Water flows through each of the tubes at a rate of 1kg/s with an inlet temperature of 30°C. The steam in the condenser shell condenses at the rate of 430kg/s at a temperature of 50°C. If the heat of vaporization is 2.326MJ/kg and specific heat of water is 4kJ/(kg.K), the effectiveness of the heat exchanger is _____ (rounded off to 3 decimal places).
