An oil cooler is in the form of a single shell 4 tube heat exchanger in which oil passes through the tubes and cool water passes through the shell. Water comes in at 15C and leaves at 25C and has a mass flow rate of 20 kg/min. Oil enters at 35C with a mass flow rate of 30 kg/min. Cp of oil is 2.13 kJ/KgC and that of water is 4.18 kJ/kgC. If the surface area of the heat exchanger is 0.5 m2, calculate the overall heat transfer coefficient. Assume the heat exchanger is adiabatic with regards to the surroundings.
