Solution:
In which type of Kaplan turbine runner does the velocity of whirl at the inlet become smaller than the blade velocity?
Solution:
In the outlet velocity triangle of a Kaplan turbine, the angle β2 is 30°. The axial velocity Vf2 is 5 m/s. What is the relative velocity Vr2 of the flow at the outlet?
Solution:
For a Kaplan turbine, the whirl velocity at the inlet of the turbine is given to be 18 m/s. The blade velocity is given as 25 m/s. What is the hydraulic efficiency for a head of 50 m? Take g = 10 m/s²
Solution:
The velocity of flow at the runner inlet of a Francis turbine is 10 m/s, and the blade velocity is 5 m/s. The volume flow rate of water is 25 m³/s. Calculate the power generated by the turbine.
