1,711 kg/hr of air flows through a counter-current heat exchanger. On the other side of the 250 kg/hr of milk flows through the heat exchanger from a pasteurization process at 80°C and requires cooling to 30°C for packaging and storage. What will be the temperature of air outlet in the exchanger if it enters at 18°C? Consider that the Cp of milk is 1.05 cal/(g °C).

Answer #1

Cp of milk is 1.05cal/g°c which is also equal to 4.39kj/kg°c.So I have written directly 4.39kj/kg°c.

Thank you...
