Question:

An adiabatic heat exchanger is to cool ethylene glycol (cp = 2.56 kJ/kg ∙ °C) flowing at a rate of 2 kg/s from 80 to 40°C by water (cp = 4.18 kJ/kg ∙ °C) that enters at 20°C and leaves at 55°C. Determine
(a) The rate of heat transfer and
(b) The rate of exergy destruction in the heat exchanger.
