. Aventurimeter is used for measuring the flow of petrol in a pipeline inclined at 35° to horizontal. The sp. gravity of the petrol is 0.81 and throat area ratio is 4. If the difference in mercury levels in the gauge is 50 mm, calculate the flow in m'/s if the pipe diameter is 300 mm. Take venturim- 3, [Ans. 0.07 m²/s] eter constant = 0.975.
