Identify the incorrect statement, from the following options:The specific speed of a hydraulic turbine (given N = RPM, P = power output, H = input head to a turbine design, NS is its specific speed)_____.

• A. Gives RPM of a turbine with the same hydraulic efficiency as the original, i.e., same design
• B. Is NS = NP/H2
• C. NS = NP0.5/H1.25
• D. RPM of a geometrically and dynamically similar turbine which will develop 1 kW power under 1 m
