24.
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
counter flow with process stream on shell side.
counter flow with process stream on tube side.
parallel flow with process stream on shell side.
parallel flow with process stream on tube side.
Answer: Option

@Bajwa.

More corrosive fluids are passed through the tubes. Also, the fluid with the greatest fouling tendency is usually passed through the tubes where cleaning is easier.

Counter flow because aqueous solution outlet temp can be greater than the steam outlet temp and also shell side because the presence of baffles increases the velocity of the aqueous solution, and the higher the velocity, the more heat gained by the aqueous solution.
