Question

6) Water at 90 °F flows from a large vessel through a pipe.Before exiting, the water flows through a venturi meter(constricted section). Energy losses are negligible. Note:Table B-1 p. 761

contains properties of water at various temperature. (a) Carefully sketch and label the energy line and hydraulic grade line.(b) If a manometer were placed in the venturi at point “X", would the fluid rise above the pipe or be below the pipe?(c) If a pitot tube were placed in the venturi at point “X", how high would the fluid rise?(d) The diameter of the pipe and the venturi at point “X" are 6" and 4", respectively.Calculate the height (h) at which cavitation occurs.
