A penstock 1 m in dimeter and 10 km long carries water from a reservoir to an impulse turbine. If the turbine is 83% efficient, what power can be produced by the system if the upstream reservoir elevation is 650 m above the turbine jet, and the jet dimeter is 16.0cm? Assume f=0.016, and neglect head losses in the nozzle. What should dimeter of the turbine wheel be if it is have an angular speed of 360 rpm? Assume ideal conditions for the bucket design ( = 1 2 )
