Overview

Engineering reference data for Lpg Pipeline Pressure Drop in gases and compressed air.

Key Formulas

Ideal Gas Law

$PV = nRT$

Pressure × Volume = moles × gas constant × temperature.

Boyle's Law

$P_1 V_1 = P_2 V_2$

At constant temperature.

Charles's Law

$\frac{V_1}{T_1} = \frac{V_2}{T_2}$

At constant pressure.

Variables

Symbol	Description	Unit
$P$	Pressure	Pa
$V$	Volume	m³
$T$	Temperature	K
$R$	Gas constant	8.314 J/(mol·K)

Unit Conversions

For engineers working with both imperial and metric systems, the following conversions are essential when interpreting LPG pipeline resistance and pressure drop data:

From	To	Conversion Factor
Gallons per minute (gpm)	Liters per second (l/s)	1 gpm = 0.075 l/s
Feet of head	Kilopascals (kPa)	1 ft head = 3.0 kPa

Diagram Reference

The original engineering data includes diagrams depicting:

Resistance (feet of head of liquid LPG per 100 ft of pipeline) versus flow rate in gpm.
Pressure Drop (kPa per 100 m of pipeline) versus flow rate in l/s.

These diagrams are generated for *steel pipes, Schedule 40.
