Question

1- Water at a rate of 1.5 kg/sec is heated from 45°C to 80°C, using a shell and tube heat exchanger by an oil which is enter at 135°C and leaves at 85°C. The overall heat transfer coefficient is 350 W/m².°C, The specific heat of the water is 4180 J/kg. Calculate the heat exchanger surface area if the two fluids are in: a) Parallel flow arrangements. b) Counter flow arrangements. c) Discuss the previous results and give your opinion.
