The volume flow rate into a Kaplan turbine is Q m3/s. 0.10Q m3/s volume of water do not flow over the runner blades. What further information is required to find the volumetric efficiency (numerical value) of the Kaplan turbine?

The volume flow rate into a Kaplan turbine is Q m3/s. 0.10Q m3/s volume of water do not flow over the runner blades. What further information is required to find the volumetric efficiency (numerical value) of the Kaplan turbine? Correct Answer No further information is required

The volumetric efficiency of the Kaplan turbine is given by Q – ΔQ/ Q. In this problem, ΔQ = 0.1Q. Thus, Q – ΔQ = 0.9Q. Hence, we get volumetric efficiency as 90%. The problem can be solved with the available information.
