Q9. (Hydrodynamics) A fluid flows through a venturi meter which is inclined at 30° from the vertical. The inlet has a diameter of 200 mm and is located below the throat which has a diameter of 80 mm.
The distance between the inlet and throat measured along the venturi centre line is 160 mm. The differential pressure is measured by a U tube manometer with the branches in contact with the meter fluid.
The level difference in the manometer is constant at 300 mm of mercury.
Calculate EACH of the following:
(a) The differential pressure; (3)
(b) The increase in kinetic energy between the inlet and the throat; (5)
(c)The fluid velocities at the inlet and throat; (4)
(d) The mass flow rate of fluid in tonnes per our. (4)
Note: Relative density of mercury = 13.6
Relative density of fluid = 0.88
Coefficient of discharge Ca = 0.97.
