32.
Steam is to be condensed in a shell and tube heat exchanger, 5 m long with a shell diameter of 1 m. Cooling water is to be used for removing the heat. Heat transfer co-efficient for the cooling water, whether on shell side or tube side is the same. The best arrangement is

Steam is lighter than water it moves freely without any external force in upward direction water will flow in downwards. And water has fouling tendency so for cleaning purpose it should be in tubes.

Can anyone give me an explanation that why we are using vertical heat exchanger if steam is going to condense then there are a chances that it may further reduce the temperature of steam feed at the bottom of the shell?

Good explanation @Ajay Ramani.

This answer is may be wrong.
Why is steam a corrosive and damage shell of the exchanger?
