Question:

Oil in an engine is being cooled by air in a crossflow heat exchanger, where both fluids are unmixed. Oil (c_ph= 2047 J/kg·K) flowing with a flow rate of 0.026 kg/s enters the tube side at 75°C, while air (c_pc= 1007 J/kg·K) enters the shell side at 30°C with a flow rate of 0.21 kg/s. The overall heat transfer coefficient of the heat exchanger is 53 W/m²·K and the total surface area is 1 m². If the correction factor is F = 0.96, determine the outlet temperatures of the oil and air.
