# Horsepower for Impulse Water Turbine

H

#### Hector Lopez

I'm building a water impulse turbine. The tubine is 10 inches in daimeter, receives 100 psi water flow and moves a shaft at 1600 rpm. I want to know how many horse power it may produce.

From an old fluid mechanics text:

you have to use consistent units.

All I want to know are the elements I have to take into consideration to calculate hp in a water impulse turbine. Something like: water flow by xxx by bba equal to hp.

Thanks a lot.

hemalo,

You'll have to test it. It is the same for calculating pump horse power.

So if you have a 2 HP pump delvering 100 psi at your flow, that will be close to what you get in your set up,

good luck

Okay,

From an old Crane Fluid Flow Handbook,

Brake Horse Power(BHP)= GPM*PSI/(1714*Turbine Efficiency).

Beyond that, you have to go into the detail design, and you'll have to talk to a design engineer and design staff.
