5.24 A counterflow 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 18 L/s. Hot water is being used to heat the toluene. The water enters the heat exchanger at 70°C and at a volumetric flow rate of 13 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).
