Turbine Rotative Speed Calculator
Posted by Dinesh onUse this simple turbine rotative speed calculator computes the highest practicable speed by the relation of the specific speed of francis turbines, propeller-type turbines to the head.
The speed should be as high as practicable as higher the speed the less expensive will be the turbine and generator and the more efficient will be the generator.
Francis turbines, Propeller-type Turbines Specific Speed Calculation
Formula:
Francis turbines : ns = 900 / √ H USCS (or) 1900 / √ H SI
Propeller-type turbines : ns = 1000 / √ H USCS (or) 2100 / √ H SI
