6. A double overhung impulse turbine of 85% efficiency is direct connected to a 30,000 kw generator of 95% efficiency. Elevation of headwater level is 2730 ft. above sea level, elevation of tailwater level is 1260 ft. above sea level, turbine setting is 12 ft., velocity of flow in penstock is equal to 0.025/2gh, loss of head due to friction is 2% of gross head. Compute the flow through the turbine in ft³/s.
