The specific speed of turbine is ________ where N is the speed of the turbine, P is power generated, Q is the rate of flow and H is the head available.
1
\({N_s} = \frac{{N\sqrt Q }}{{{H^{\frac{5}{4}}}}}\)
2
\({N_s} = \frac{{N\sqrt Q }}{{{H^{\frac{3}{4}}}}}\)
3
\({N_s} = \frac{{N\sqrt P }}{{{H^{\frac{5}{4}}}}}\)
4
\({N_s} = \frac{{N\sqrt P }}{{{H^{\frac{3}{4}}}}}\)
5
\({N_s} = \frac{{N\sqrt P }}{{{H^{\frac{3}{2}}}}}\)
