How to Calculate Francis Turbine Speed Ratio?
Francis Turbine Speed Ratio calculator uses Speed Ratio of Francis Turbine = Velocity of Vane at Inlet for Francis Turbine/(sqrt(2*Acceleration due to Gravity*Head at Inlet of Francis Turbine)) to calculate the Speed Ratio of Francis Turbine, The Francis turbine speed Ratio formula is the ratio of tangential velocity to theoretical velocity in the turbine. Speed Ratio of Francis Turbine is denoted by Ku symbol.
