• ### What is pressure drop Alicat Scientific

Pressure drop is the amount of line pressure that is permanently lost as gas passes through an instrument in the gas line. This pressure loss is due to the frictional resistance of the components the gas touches. Every instrument and fitting in a line induces some pressure drop even the pipe walls generate some friction which causes a small

• ### What is the difference between pressure and head

2016-5-31 · The pump selection of a pump is driven by the following main parameters Head (H)Flow rate (Q)Fluid characteristics (ρ γ T .) Sometimes head can be confused with pressure during pump choice. As a matter of fact there is a strict relation between them which is defined by the fluid specific gravity so the relation is fluid dependent.

• ### What Is Osmosis Definition Types Osmotic Pressure

Osmotic pressure is defined as the minimum pressure applied to a solution to stop the flow of solvent molecules through a semipermeable membrane. The osmotic pressure of a solution is proportional to the molar concentration of the solute particles in the solution. π = iCRT is the formula used for finding the osmotic pressure of a given solution.
