A 1 shell-pass, 6 tube-pass shell and tube heat exchanger uses 20 kg/s of river water at 10o C, on the shell side, to cool 8 kg/s of processed water flowing at 2 m/s from 80o C on the tube side. The overall heat transfer coefficient is 85 W/m 2 -K and exchanger surface area is 200 m 2 . At what temperature would the process water and the coolant (i.e. the river water) be? Specific heat capacity of water = 4.184 J/go C (Answer: Thot, o = 53.4°C, Tcold, o = 20.6°C) Practice Question 5. Hot water in shell side at an inlet temperature of 11

Question
A 1 shell-pass, 6 tube-pass shell and tube heat exchanger uses 20 kg/s of river water at 10o C, on the shell side, to cool 8 kg/s of processed water flowing at 2 m/s from 80o C on the tube side. The overall heat transfer coefficient is 85 W/m 2 -K and exchanger surface area is 200 m 2 . At what temperature would the process water and the coolant (i.e. the river water) be? Specific heat capacity of water = 4.184 J/go C (Answer: Thot, o = 53.4°C, Tcold, o = 20.6°C) Practice Question 5. Hot water in shell side at an inlet temperature of 116°C and an outlet temperature of 49°C is used to heat water flowing in tube side at 2.5 kg/s from 21°C to 55°C in a one-shell-pass, two-tube-pass heat exchanger. The outside surface area of the tubes is found to be Ao = 9.5 m2. Assuming water has a specific heat Cp = 4187 J/kg-°K, determine the mean temperature difference LMTD, and the overall heat-transfer coefficient Uo. (Answer : 42.4°Cx0.82 = 34.8°C, 1078.6 W/m2 K
