İ. 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 discharge. Take C, = 0.98. ii. If in the problem 13, instead of water, oil of sp. gr. 0.8 is flowing through the venturimeter, determine the [Ans. 154.02 lit/s] rate of flow of oil in litres/s. [Ans. 173.56 lit/s]

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.
