Question

Oil is cooled from an initial temperature of 96°C to 60°C by water in an adiabatic concentric
heat exchanger. The flow rates for the oil and water are 0.7 kg s-1 and 0.4 kg s-1 respectively.
If water enters the heat exchanger with a temperature of 20°C, what is the temperature of
the water when it leaves the heat exchanger? State any assumptions made in the
calculation.
Assume the following heat capacities are constant as a function of temperature, CP(Oil) =
2131 J kg-1 K-1 and Cp(Water) = 4178 J kg-1 K-1.
