Question

1) A glass manometer with oil as the working fluid is connected to an air duct. Which of the following picture is CORRECT? a or b

2) A device measured stagnation pressure is called?

a) barometer

b) Piezometer

c) Pitot tube

d) manometer

The image depicts two diagrams of a Venturi tube, which is used to demonstrate the principle of fluid dynamics. **Top Diagram:** - The diagram shows a fluid flowing from left to right through a Venturi tube. - The tube has a wide section and tapers to a narrower section, then widens again. - There is a U-shaped manometer connected to the narrow section of the tube. - In the narrow section, the fluid level in the manometer is higher compared to the wide section, indicating lower pressure at the narrow section due to increased velocity, in accordance with Bernoulli's principle. **Bottom Diagram:** - Similar to the top diagram, it shows a fluid flowing from left to right. - The configuration of the Venturi tube is the same, with a wide section narrowing and then widening again. - The U-shaped manometer shows fluid at different levels. - The fluid level in the manometer is higher at the wider part, indicating higher pressure and lower velocity compared to the narrower section. Both diagrams illustrate how fluid velocity increases as the cross-sectional area decreases, resulting in a pressure drop, demonstrating Bernoulli's principle. This is crucial in various applications like measuring fluid flow rates.
