The peripheral velocity = 0.26$\sqrt{29H}$ and the radial velocity of flow at inlet is 0.96$\sqrt{29H}$ The wheel runs at 150 r.p.m and the hydraulic losses in the turbine are 22% of the available energy, assuming radial discharge
Determine.
1] The guide blade angle.
2] The wheel vane angle at inlet. …
