A venturi meter of 150 mm × 75 mm size is used to measure the flow rate of oilhaving specific gravity of 0.9. The reading shown by the U tube manometer
connected to the venturi meter is 150 mm of mercury column. Calculate the
coefficient of discharge for the venturi meter if the flow rate is 1.7 m3/min. (Note: The size of venturi meter generally specified in terms of inlet and throat diameters)
