Volume flow and pressure loss in CTS - Copper Tube Sized CPVC (Chlorinated Poly Vinyl Chloride) tubes
Chlorinated Poly Vinyl Chloride (CPVC) is a thermoplastic pipe and fitting material made with CPVC compounds meeting the requirements of ASTM Class 23447 as defined in ASTM Specification D1784. CPVC applications are for potable water distribution, corrosive fluid handling in industry, and fire suppression systems.
Head Loss (ft H2O/100 ft)
Head loss in CTS - Copper Tube Sized CPVC (Chlorinated Poly Vinyl Chloride) tubes:
- 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
Pressure Loss (kPa/m)
Pressure loss in CTS - Copper Tube Sized CPVC (Chlorinated Poly Vinyl Chloride) tubes:
- 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
Example - Water Flow in Copper Tube
1 l/s of water flows through a 1" copper tube. From the figure below we estimates the velocity to be approximately 1.8 m/s and the pressure loss to be approximately 1.7 kPa/m.
