A shell-and-tube heat exchanger is arranged as a single shell and two-tube pass. and 135 thin-walled pipes, each 12.5 mm in diameter. total heat transfer surface area 47.5 m2 has been determined. The water flowing through the pipes It enters the exchanger at a temperature of 150C and a flow rate of 6.5 kg/s. used to heat water Exhaust gas enters the heat exchanger at a temperature of 2000C and a flow rate of 5 kg/s. total heat Since the transfer coefficient is 200 W/m2C; a) Calculate the outlet temperature of the water. b) Calculate the exhaust gas output. (The average temperature of the water is 300C and the average temperature of the exhaust gas The physical properties of exhaust gas can be considered the same as air.) is 1300C.
