The diameter of the pipe at the entrance (point 1) is0.6 m and at the narrowing in the pipe (point 2) the diameter is 0.3 m. The pressure gauge in point 1shows the pressure P1 = 300 kPa and the velocity V1 = 2.5 m/s.One is worried about cavitation in the pipe. Use table A-3 based on a water temperatureat 15°C for the calculations. Atmospheric pressure is 101.325 kPa.P1Figure 4, sketch for task 5a) Explain what cavitation is and why it is undesirable.b) State the assumptions and calculate the speed in the constriction, V2.

1. Solve the following and draw the figures Í. A 30 cm x 15 cm venturimeter is inserted in a vertical pipe carrying water, flowing in the upward direction. A differential mercury manometer connected to the inlet and throat gives a reading of 30 cm. Find the [Ans. 154.02 lit/s] ii. If in the problem 13, instead of water, oil of sp. gr. 0.8 is flowing through the venturimeter, determine the [Ans. 173.56 lit/s] III. The water is flowing through a pipe of diameter 30 cm. The pipe is inclined and a venturimeter is inserted in the pipe. The diameter of venturimeter at throat is 15 cm. The difference of pressure between the inlet and throat of the venturimeter is measured by a liquid of sp. gr. 0.8 in an inverted U-tube which gives a reading of 40 cm. The loss of head between the inlet and throat is 0.3 times the kinetic head of the pipe. [Ans. 22.64 lit./s] discharge. Take Ca = 0.98. rate of flow of oil in litres/s. Find the discharge.
