The diagram below represents how water is funnelled into a pipe and directed to aturbine at a hydroelectric power plant. The force of the falling water rotates theturbine. Each second, 200 m3 of water is funnelled down a vertical shaft to the turbine below. The vertical height through which the water falls upon reaching the turbine is 150 m. Ignore the effects of friction. NOTE: One m3 of water has a mass of 1 000 kg. Calculate the mass of water that enters the turbine each second. Calculate the kinetic energy of this mass of water when entering the turbine. Use the work- energy theorem. Calculate the maximum speed at which this mass of water enters the turbine.
