Question: help with draw . quickly Q5/ Water ( Cp =4.18 kJ/kg.C) at ( 30 C) is available for use as a coolant in counter flow
Q5/ Water ( Cp =4.18 kJ/kg.C) at ( 30 C) is available for use as a coolant in counter flow double pipe heat exchanger whose total surface area is ( 2 m). The water is to be to cool oil ( Cp=2.3 kJ/kg.C) from an initial temperature of ( 150 C). Because of other circumstances, an exit water temperature greater than ( 90 C) cannot be allowed. The exit temperature of the oil must not be below ( 56 C). The over all heat transfer coefficient is ( 290 W/mC). Estimate the flow rate of oil & water. Good Luck
