Axial Load on Horizontal Francis Turbine

12/11/2006 12:30 AM

I would be pleased, if some can help me by giving guidance to calculate axial load on Horizontal Francis Turbines.

Available techincal data,

Maximum power put put _1.4 MW

Runner Diameter _ 430 mm

Shaft Diameter _ 250 mm

Best Regards,

Asitha from Sri Lanka

The upstream minus the downstrean pressure times the area of the vanes and hub plus any mass load from the vanes.

Area in^2 x pressure delta in psi = lbs force.

I agree. Francis turbine is basically not subject to dynamic loads during work. So, the statement looking for pressure differential plus mass loads is correct. I think this would be the main doubt.

PS: also, you can use SI units: kg, N, m, Pa (= N/m2)
