Unformatted text preview: cutting through the water exiting the bucket. Note that this is a moving control volume , moving to the right at speed R . We also cut through the welded joint between the bucket and the turbine wheel, where the force F bucket on wheel is to be calculated. Because of Newton’s third law, the force acting on the control volume at this location is equal in magnitude, but opposite in direction, and we call it F bucket on wheel . R A e e CV F wheel on bucket F bucket on wheel 1 2 V j A j j Since the pressure through an incompressible jet exposed to atmospheric air is equal to P atm , the pressure at the inlet (1) is equal to P atm , and the pressure at the exit (2) is equal to P atm . (b) To do : Calculate the power delivered to the turbine wheel. Solutions for parts (a) and (b) to be completed in class....
