A Venturi flowmeter is shown here again. The wide part has a diameter of 5.5 cm and the narrow part has a diameter of 3.5 cm. If water flows through the wide part at 2.5 m/s . In a previous Q&A Example, we found that the flow through the narrow part has a speed of 6.2 m/s.
The gauge pressure in the wide part is 15 mmHg (or 15 torr). What is the pressure in the narrow part?
