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.
