Air Discharge Hose

Overview

Engineering reference data for Air Discharge Hose 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

Compressed Air Hose Diameter Reference

Unit Conversions

The following conversions are essential for calculations involving air discharge hose systems:

• $1 \text{ psig} = 6.9 \text{ kPa} = 0.069 \text{ bar}$
• $1 \text{ ft (foot)} = 0.3048 \text{ m}$
• $1 \text{ scfm} = 0.472 \text{ nl/s}$

Operational Parameters

The volume of air discharged is dependent on the hose length and supply pressure. For a 100-foot hose, typical operational data is provided for pressures ranging from 30 to 90 psi.
