C- Hot engine oil is to be cooled in a double-tube counter-flow heat exchanger. The copper inner tubes have a diameter of 2.5 cm and negligible thickness. The inner diameter of the outer tube (the shell) is 4 cm. Water flows through the tube at a rate of 0.42 kg/s, and the oil through the shell at a rate of 0.91 kg/a. Taking the average temperatures of the water and the oil to be 52 C and 95°C, respectively, determine the overall heat transfer coefficient of this heat exchanger. Nu or Turbulent flow
