Hydropower Calculators
Hydroelectric power from head and flow, water head from pressure, pipe head loss, flow rate and annual energy.
Hydropower
Water Head Calculator
Gross and net head for a hydro scheme after pipe friction losses.
net head = gross head − friction loss
Also called gross head calculator · net head hydro
Hydropower
Pipe Head Loss Calculator
Friction head loss in a pipe run using Hazen-Williams, with fittings expressed as extra length.
h_f = 10.67 × L × Q^1.852 ÷ (C^1.852 × d^…
Also called friction loss calculator · head loss in pipe
Hydropower
Flow Rate Calculator
Volumetric flow rate from pipe area and velocity (Q = A·v), in m³/s, L/min and gallons per minute.
Q = A × v = volume ÷ time
Also called volumetric flow rate · q = av
Hydropower
Annual Energy Output Calculator
Annual energy from a generator using its rated power and capacity factor, with the value.
AEP = rated kW × 8760 × capacity factor ×…
Also called aep calculator · yearly generation
Key hydropower formulas
| Hydropower | P = ρ g Q H × efficiency |
|---|---|
| Water Head | net head = gross head − friction loss |
| Pipe Head Loss | h_f = 10.67 × L × Q^1.852 ÷ (C^1.852 × d^4.87) |
| Flow Rate | Q = A × v = volume ÷ time |
| Annual Energy Output | AEP = rated kW × 8760 × capacity factor × availability |
