At a hydro electric power plant site, available head and flow rate are $$24.5$$ $$m$$ and $$10.1{m^3}/s$$ respectively. If the turbine to be installed is required to run at $$4.0$$ revolution per second ($$rps$$) with an overall efficiency of $$90\% $$, the suitable type of turbine for this site is _______________.

If there are $$'m'$$ physical quantities and $$'n'$$ fundamental dimensions in a particular process, the number of non-dimensional parameters is

Kaplan turbine is

In terms of speed of rotation of the impeller $$N$$, discharge $$Q$$ and a change in total head $$H$$, through the machine,the Specific Speed for a pump is ________________ (fill the blank)
