Question

Accepted Answer

The interview questions cover topics like NPSH, cavitation, shell and tube heat exchangers, cooling towers, resume, and distillation columns.

NPSH stands for Net Positive Suction Head and is a measure of the pressure available at the suction port of a pump to prevent cavitation.
Cavitation is the formation of vapor bubbles in a liquid due to rapid changes in pressure, which can damage pump components.
Shell and tube heat exchangers can face issues like fouling, corrosion, and leakage, which can be solved by regular maintenance, cleaning, and using corrosion-resistant materials.
Cooling towers are used to remove heat from a building or industrial process by evaporating water, with the principle of heat rejection through the evaporation of water.
Distillation columns are used to separate components in a liquid mixture based on their boiling points, with the higher boiling point components condensing at the top and the lower boiling point components vaporizing at the bottom.
