LPG Pipes - Pressure Loss vs. Gas Flow

Resistance and pressure loss in liquid LPG pipes.

Resistance in LPG pipelines expressed as feet of head of liquid LPG-gas per 100 feet pipeline - and pressure drop expressed as kPa per 100 m pipeline - are indicated in the diagrams below. The diagrams are made for steel pipes schedule 40.
