A storage reservoir supplies water to a pressure turbine under a head of 20 m. When the turbine draws 0.5 m^3/s of water, the head loss in the 300 mm-diameter supply line amounts to 2.5 m. -Determine the pressure intensity at the entrance of the turbine -If a negative pressure of 30 kPa exists at the 600mm-diameter section of the draft tube 1.5m below the supply line (point 3), estimate the energy absorbed by the turbine in kilowatts neglecting all frictional losses between the entrance and exit of the turbine. -Assuming a turbine efficiency of 85%, find the power output of the turbine
