1.A venturi meter installed in a pipe with a 38.10cm diameter has a throat diameter of 21.24cm. The static gage presure upstream of the venturi is 172.4kPa. The average fluid velocity in the pipe is 7.62 m/s. The fluid flowing is water. If cavitation is just beginning at the throat of the venturi, what is most nearly the absolute vapor pressure of the water at the throat?
2.The tractor boom supports a uniform mass of 500 kg in the bucket which has a center of mass at G. Determine the force in each hydraulic cylinder AB and CD and the resultant force at pins E and F. The load is supported equally on each side of the tractor by a similar mechanism.
