Ask Alicat: What Is Pressure Drop?

Details

Description

Pressure drop is the amount of line pressure that is permanently lost as gas passes through an instrument in a gas line. Alicat Scientific demonstrates the importance of pressure drop for gas flow processes and shows how you can greatly reduce pressure drop by using its Whisper Series of mass flow instruments.

Pressure drop is the amount of line pressure permanently lost as gas passes through an instrument. This loss is due to the frictional resistance of the components the gas touches. Every instrument and fitting in a line induces some pressure drop.
