9) Water at 90 °F flows from a large vessel through a commercial steel pipe. Beforeexiting, the water flows through a venturi meter (constricted section). DO NOTNEGLECT ENERGY LOSSES. Note:

Table B-1 p. 761 contains properties of water atvarious temperatures. various lem(a) The diameter of the pipe and the venturi at point "X" are 3" and 1", respectively.The length of the straight section of pipe is 15 ft and the venturi is 10 ft from the entrance. The minor loss coefficient through the venturi meter is KL = 0.22 through the constriction and 0.4 through the expansion. The entrance loss coefficient is KL = 0. 5.Calculate the height (h) at which cavitation occurs. (b) Compare this answer with that obtained when energy losses were neglected (Note- you have this solution from hw #6). Explain why these results make sense in terms ofthe role of friction. (c) Carefully sketch and label the energy grade line and hydraulic grade line.
