Water (cp = 4180 J/kg°C) enters a thin-walled double-pipe counter-flow heat exchanger at 22°C at a rate of 1.5 kg/s. This water is to be used to cool oil (cp = 2200 J/kg°C) from 150°C to 40°C at a rate of 2 kg/s. If the overall heat transfer coefficient of this heat exchanger is 32.5 kW/m2°C and the length of the tube is 6 m, the diameter (in cm) of the tube will be _____. (Answer up to one decimal place)
    Correct answer is '2.5'. Can you explain this answer?

    Water (cp = 4180 J/kg°C) enters a thin-walled double-pipe counter-...
    The rate of heat transfer from the water to the oil is:
    = 2 * 2.2 * (150 - 40) = 484 kW
    The outlet temperature of the water is determined from:
    The logarithmic mean temperature difference is:
    Then, the overall heat transfer coefficient becomes:
