Solve Problem 5.29 for a parallel flow heat exchanger.

Problem 5.29

A counter flow heat exchanger is being used to heat a flow of liquid toluene. The toluene enters the heat exchanger at 5°C with a volumetric flow rate of 10 L/s. Hot water is being used to heat the toluene. The water enters the heat exchanger at 70°C and a volumetric flow rate of 18 L/s. The UA product of the heat exchanger is 25 kW/K. Determine the outlet temperatures of both fluids (°F) and the heat transfer rate between them (kW).
