Sir can you help me with this problem 🙂? A cold liquid tsp heat 295 kj/kg K) at 10 kg/ min is to be heated from 25°C to 55°C in a heat exchanger. The task is accomplished by extracting heat from hot water (sp. heat 4.186 kj/kg K) available at mass flow rate 5 kg/min and inlet temperature 85°C. Should the thermal engineer make design calculation based on parallel flow or counter flow configuration 7 State the reason thereof.
