QUESTION 2 [25 MARKS A double-pipe heat exchanger is designed to condense saturated steam as Figure 1. Water flows at an average temperature of 37.8C and an average velocity of 2.6 m's. If the inner surface temperature of the inner pipe is 65.6C and the heat exchanger is 3.5 m long, answer the following a) Determine the heat transfer rate from the steam to water. 112 Marks CO2, PO2, C41 b) Determine the temperature rise per meter of water. 14.5 Marks (CO2, PO2, C31 c) Determine the amount of condensate. 13 Marks CO2, PO2, C31 INTIA Saturated steam 80C Double-pipe Heat Exchanger Water Water Condensate 2-in schedule 40 steel pipe Steam Water 1-in schedule 40 steel pipe
