SUMMARY
The discussion focuses on calculating the pressure difference in a Venturi meter, specifically with a gauge pressure of 40 kPa at the inlet and a vacuum of 38 mm mercury at the throat. The fluid in the Venturi meter is oil with a relative density of 0.8. Participants emphasize the need to determine the height of the fluid column in a differential U-tube manometer, which involves summing the pressures exerted by both mercury and oil. The final answer for the difference in mercury levels is 0.359 m.
