The rotor of a kaplan turbine is 2.8m in dia. at theblade tips and 0.9m at the hub. Its speed of rotation is 110r/min.Water enters the rotor without shock, making an angle of 37° to theaxial direction at the mean dia and rotor has a blade exit angle of58° to the axial direction at the mean diameter. The availablepressure head is 6.5m .Determine 1) the inlet angle of the rotorblades at the mean dia. 2) the hydraulic efficiency and 3) themaximum mechanical power developed if the mechanical efficiency is95%. make a neat drawing showing the layout and dimensions of theturbine and draw the inlet and exit velocity diagrams reasonably toscale
