Fluid Mechanics (Pressure Distribution in Fluids)
Indicate whether the statements are correct or incorrect.
1. In a fluid at rest, the pressure at a point varies with direction.
2. In a fluid at rest the pressure at a constant level will be equal at all locations.
3. The pressure on the base of a liquid column will depend upon the shape of the column.
4. The pressure over a free surface of a fluid at rest will vary with location.
5. For low pressure measurement a manometric fluid with low density will be better.
6. In a manometer, the fluid column will rise if the pressure measured is above the atmosphere.
7. In a manometer, the fluid column will fall if the pressure inside is less than atmospheric.
8. The vacuum gauge reading will increase as the absolute pressure decreases.
9. The absolute pressure is equal to the vacuum gauge reading.
10. Absolute pressure = atmospheric pressure – vacuum gauge reading.
