Online aerodynamics / hydrodynamics calculator to calculate turbine specific speed from the user inputs.

The turbine specific speed is a quantity derived from dimensional analysis. For a specific turbine type (Francis, Kaplan, Pelton), the turbine efficiency will be primarily a function of specific speed.

Specific Speed of Turbine Calculation

Formula:

n s = N P H 5 4

where,
N = Wheel speed
P = Power
H = Water head
ns = Turbine specific speed
