A hot engine oil (Cp=2094 J/kg.∘C) is to be cooled by ethylene glycol solution (Cp=4190 J/kg.∘C ) in a counter flow double pipe heat exchanger. The engine oil enters at 1 kg/s at 110∘C while the ethylene glycol solution enters at 0.5 kg/s at 20∘C. The inner tube is thin-walled and has a total area of 6 m2. Determine the outlet temperatures if the overall heat transfer coefficient is 550 W/m2⋅K. (12 marks)
