In a co-current double pipe heat exchanger used for condensing saturated steam over the inner tube, if the entrance and exit conditions of the coolant are interchanged, then the rate of condensation will

Question

Quizplus · Accepted Answer

The rate of condensation primarily depends on the temperature difference between the saturated steam and the coolant. Interchanging the entrance and exit conditions of the coolant in a co-current flow does not change the overall average temperature difference driving the heat exchange process. Therefore, the rate of condensation remains unchanged.
