FAQ

What is Head of a turbine given specific speed?

The Head of a turbine given specific speed formula is defined as the ratio of product of speed and square root of power to the specific speed whole raised to the power of 4/5 and is represented as H=((N*sqrt(P))/N_s)^(4/5) or Head=((Speed*sqrt(Power))/Specific speed of a turbine)^(4/5). Speed of a machine/body in rpm, Power is the amount of energy transferred in unit time and Specific speed of a turbine is the speed which produces 1KW of power under 1m head.

How to calculate Head of a turbine given specific speed?

The Head of a turbine given specific speed formula is defined as the ratio of product of speed and square root of power to the specific speed whole raised to the power of 4/5 is calculated using Head=((Speed*sqrt(Power))/Specific speed of a turbine)^(4/5). To calculate Head of a turbine given specific speed, you need Speed (N), Power (P) and Specific speed of a turbine (N_s). With our tool, you need to enter the respective value for Speed, Power and Specific speed of a turbine and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Head?
