Consider a concentric tube heat exchanger with hot and cold water inlet temperatures of 202 and 35°C respectively. The flow rates of the hot and cold fluids are 42 and 84 kg/h, respectively. Assume the overall heat transfer coefficient is 178 W/m2k. cc = 4186 J/kgk, ch = 4302 J/kgK What is the maximum heat transfer rate that could be...

Hot air enters a heat exchanger at 350°C and exits at (149°C. The heat extracted is used to boil (0.263) kg/s of 100°C water (from saturated liquid to saturated steam). The heat exchanger is a single-shell shell-and-tube heat exchanger with two tube passes. The overall heat transfer coefficient for the hot side is 240 W/(m2°C). Assume a constant specific heat for air of Cp = 1.005 kJ/(kgC). The pressure of the hot air and the boiling water is P =...

Q3. Oil of unknown properties is heated in a shell-and-tube heat exchanger with one shell pass and 20 tube passes. The oil flows through the shell, and hot water flows inside the single copper tube that has an inner diameter of 20 mm, a wall thickness of 2 mm, and a length of 3 m per pass. The water enters at 360 Kat a mass flow rate of 0.2 kg/s and leaves at...

Question 4: (70 Marks) To recover some of the waste heat in the exhaust of a gas turbine, a heat exchanger with unmixed fluids is used. Hot exhaust gases, at Thi-425°C, flow through tubes, and the cold intake air flows across these tubes at Tci= 25°C, and Tco-210°C, The heat exchanger is designed with mass flow rates m-c 10 kg/s, heat transfer coefficients...
