A shell-and-tube heat exchanger with two-shell passes and 4-tube passes is used for cooling oil (cp = 2.0 kJ/kg·K) from 125°C to 55°C. The coolant is water, which enters the shell side at 25°C and leaves at 46°C. The overall heat transfer coefficient is 900 W/m2·K. For an oil flow rate of 10 kg/s, calculate the cooling water flow rate and the heat transfer area.

Water flowing in a long, aluminum lube is to be heated by air flowing perpendicular to the exterior of the tube. The ID of the tube is 1.85 cm, and its OD is 2.3 cm. The mass flow rate of the water through the tube is 0.65kg/s, and the temperature of the water in the lube averages 30C. The free-stream velocity and ambient temperature of the air are 10m/sand120C, respectively. Estimate the overall heat transfer coefficient for the heat exchanger using appropriate correlations from previous chapters. State all your assumptions.
Answer the following questions about heat transfer in a double tube heat exchanger.(1) In a double tube heat exchanger in which hot and cold fluids flow into a countercurrent flow, the temperature of the hot fluid dropped from 60°C to 30°C, and the temperature of the cold fluid rose from 20°C to 55°C. Calculate the heat flux [kcal/m2h] when the overall heat transfer coefficient of this heat exchanger is constant at 69 kcal/m2h℃.(2) In a double tube heat exchanger in which hot and cold fluids flow in parallel flow, the temperature of the hot fluid dropped from 60°C to 45°C, and the temperature of the cold fluid rose from 20°C to 40°C. When the heat flux of this heat exchanger is 600 kcal/m2h, calculate the overall heat transfer coefficient of this heat exchanger [kcal/m2h℃].
Consider a water-to-water double-pipe heat exchanger whose flow arrangement is not known. The temperature measurements indicate that the cold water enters at 20°C and leaves at 50°C, while the hot water enters at 80°C and leaves at 45°C. Do you think this is a parallel-flow or counter-flow heat exchanger? Explain.
