You are given technical specifications and are responsible for analyzing an arrangement

You are given technical specifications and are responsible for analyzing an arrangement for either parallel flow or counter flow heat exchangers, and plan to run hot motor oil through one side, and cold water through the other. W The heat exchanger will have an overall heat transfer coefficient of U = 300. and a total mK' surface area of A = 2.5 m. = The inlet temperature of the oil will be To 205C with a mass flow rate of 11,000 kg/hr, and the inlet temperature of the water will be Tw = 20C with a mass flow rate of 4000 kg/hr. J Take the specific heat of oil to be Cp,oil = 1900 and the specific heat of water to be Cp,water = 4181 J kgK kgK a) Find the outlet temperature of both the oil and water for parallel flow b) Find the outlet temperature of both the oil and water for counter flow c) Find the heat transfer rate Q for the parallel flow d) Find the heat transfer rate Q for the counter flow e) Which is the more efficient heat exchanger? Why?
