The power output of a hydraulic turbine depends on the diameter D of the turbine, the density
of water, the height H of water surface above the turbine, the gravitational acceleration g, the angular velocity
 of the turbine wheel, the discharge Q of water through the turbine, and the efficiency
 of the turbine. By dimensional analysis, generate a set of appropriate dimensionless groups.
