Calculate heat duty of heat exchanger
WebMay 22, 2024 · Example: Calculation of Heat Exchanger. Consider a parallel-flow heat exchanger, which is used to cool oil from 70°C to 40°C using water available at 30°C. The outlet temperature of the water is 36°C. The rate of flow of oil is 1 kg/s. The specific heat of the oil is 2.2 kJ/kg K. The overall heat transfer coefficient U = 200 W/m 2 K. WebSep 26, 2024 · A heat exchanger is an energy exchange system (in the form of heat) between a hot and a cold fluid. In practice, all the thermal duty of the hot fluid (fc) is transferred to the cold fluid (ff), thereby fulfilling the next energy balance: The thermal duty of a fluid in liquid state depends on the mass flowrate and the temperature differential ...
