Maximum overall efficiency

The following data refer to a Pelton wheel. Maximum overall efficiency 79%, occurring at a speed ratio of 0.46;  for nozzle = 0.97; jet turned through 165◦. Assuming that the optimum speed ratio differs from 0.5 solely as a result of losses to windage and bearing friction which are proportional to the square of the rotational speed, obtain a formula for the optimum speed ratio and hence estimate the ratio of the relative velocity at outlet from the buckets to the relative velocity at inlet.
