A STHX 1-4 heat exchanger is being used to heat a flow of liquid toluene. 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 product UA of the heat exchanger is 25 kW / K. Determine the heat transfer rate (kW) Toluene Properties: Density: 864.8 kg / m ^ 3 cp: 1,692 kJ / kgK Properties of Water: Density: 982.3 kg / m ^ 3 cp: 4,186 kJ / kgK
