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

Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
