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...read more

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...read more

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
