Brake Horsepower vs Required Flow Rate
Formel
## Well Pump Sizing **Water HP = GPM x TDH / 3960** **Brake HP = Water HP / Efficiency** The constant 3960 comes from converting GPM and feet of head to horsepower units. Submersible pump efficiency is typically 50 to 70 percent. Multiply HP by 746 to get watts.
Lösungsbeispiel
10 GPM pump with 200 ft TDH, 60% efficiency.
- 01Water HP = 10 x 200 / 3960 = 0.505 HP
- 02Brake HP = 0.505 / 0.60 = 0.84 HP
- 03Motor = 0.84 x 746 = 627 W
- 04Select a 1 HP submersible pump.
Häufig Gestellte Fragen
What is total dynamic head for a well pump?
TDH equals well depth plus drawdown plus friction loss plus delivery pressure. For a 150 ft deep well with 20 ft drawdown, 10 ft friction, and 40 psi (92 ft) delivery, TDH = 272 ft.
How do I know the pump efficiency?
Check the manufacturer pump curve. Residential submersible pumps are typically 50 to 65 percent efficient at the design point.
