Friction loss for CTS CPVC pipe is indicated in the diagrams below. 

Head Loss (ft H₂O/100 ft) 

• 1 ft H₂O = 0.4335 psi = 62.43 Lbs./Sq.Ft.
• 1 gal (US)/min =6.30888x10^-5 m³/s = 0.227 m³/h = 0.06309 dm³(litre)/s = 2.228x10^-3 ft³/s = 0.1337 ft³/min = 0.8327 Imperial gal (UK)/min
• 1 ft/s = 0.3048 m/s

Friction Loss (kPa/m)

• 1 Pa = 10^-6 N/mm² = 10^-5 bar = 0.1020 kp/m² = 1.02x10^-4 m H₂O = 9.869x10^-6 atm = 1.45x10^-4 psi (lbf/in²)
• 1 dm³(litre)/s = 10^-3 m³/s = 3.6 m³/h = 0.03532 ft³/s = 2.1189 ft³/min (cfm) = 13.200 Imp.gal (UK)/min = 15.852 gal (US)/min = 792 Imp. gal (UK)/h
• 1 m/s = 3.6 km/h = 196.85 ft/min = 2.237 mph
