A process stream of dilute aqueous solution flowing at the rate of10 Kg.s^-1 is to be heated. Steam condensate at 95°C is available for heating purpose, also at a rate of 10 Kg.s-1 . A 1 - 1 shell and tube heat exchanger is available. The best arrangement is A)Counter flow with process stream on shell side B)Counter flow with process stream on tube side C)Parallel flow with process stream on shell side D)Parallel flow with process stream on tube side

Question

Quizplus · Accepted Answer

Counter flow arrangement provides the maximum temperature difference between the two fluids over the length of the heat exchanger, leading to more efficient heat transfer. Placing the process stream on the shell side can enhance heat transfer due to better mixing and higher heat transfer coefficients.
