The number of plates in a distillation column can be found using the McCabe-Thiele method.
The McCabe-Thiele method involves constructing a graph of the distillation process and determining the number of theoretical plates required for separation.
The method takes into account the vapor-liquid equilibrium data and the reflux ratio of the column.
The number of plates can also be estimated using empirical correlations or si...
Net Positive Suction Head (NPSH) is the difference between the absolute pressure at the suction of the pump and the vapor pressure of the liquid.
NPSH is a critical parameter in pump design and operation.
It determines whether the pump will cavitate or not.
Cavitation can cause damage to the pump and reduce its efficiency.
NPSH is affected by factors such as fluid properties, pump speed, and suction piping design.
NPSH can ...

I applied via Company Website and was interviewed in Dec 2021. There were 4 interview rounds.
Design steps for a shell and tube heat exchanger
Determine the heat duty and fluid flow rates
Select the appropriate materials for the tubes and shell
Determine the number of tube passes and tube layout
Design the baffles and tube supports
Calculate the heat transfer area and pressure drop
Specify the inlet and outlet connections

Pressure drop in a column refers to the decrease in pressure as fluid flows through the column.
Pressure drop is caused by frictional resistance to flow and changes in direction of the fluid.
It can be calculated using Bernoulli's equation or by measuring pressure at different points in the column.
Pressure drop can affect the efficiency of the column and may require adjustments to the operating conditions.
Factors that ca...

NPSH stands for Net Positive Suction Head in a centrifugal pump.
NPSH is a measure of how much suction pressure is required at the pump inlet to prevent cavitation.
It is important to ensure that the NPSH available (NPSHa) is greater than the NPSH required (NPSHr) for the pump to operate efficiently.
NPSH is affected by factors such as pump speed, fluid properties, and system design.
Cavitation can occur if the NPSH availa...
Distillation is a separation process that involves heating a liquid mixture to create vapor and then cooling the vapor to get a purified liquid.
Types of distillation include simple distillation, fractional distillation, and steam distillation.
Simple distillation is used for separating components with large boiling point differences.
Fractional distillation is used for separating components with closer boiling points.
Ste...
Types of impellers in centrifugal pumps include closed, open, semi-open, and vortex.
Closed impeller: all flow enters and exits through the impeller blades
Open impeller: flow enters through the center and exits along the blades
Semi-open impeller: flow enters through the eye and exits along the blades
Vortex impeller: flow enters through the eye and exits through the periphery
Impeller selection depends on the application
