Heat and Mass Transfer A designer chooses the values of fluid flow rates and specific heats in such a manner that the heat capacities of the two fluids are equal. A hot fluid enters the counter flow heat exchanger at 100°C and leaves at 60°C. A cold fluid enters the heat exchanger at 40°C. The mean temperature difference between the two fluids is 40°C 20°C 60°C 66.7°C 40°C 20°C 60°C 66.7°C ANSWER DOWNLOAD EXAMIANS APP
