# Hoses - Water Volume Discharge Flow vs. Pressure

### Hose - Water Discharge - Imperial Units

Water discharge through 100 feet hoses - at pressures ranging 10 - 200 psi:

• 1 psi = 6.9 kPa = 0.069 bar
• 1 ft (foot) = 0.3048 m
• 1 gal (US)/min =6.30888x10-5 m3/s = 0.227 m3/h
.

### Hose - Water Discharge - Metric Units

Water discharge through 30 m hoses - at pressures ranging 0.75 - 14 bar:
