FAQs on Pressure Variation in a Fluid at Rest Video Lecture - Fluid Mechanics for Mechanical Engineering

1. How does pressure vary in a fluid at rest?
Ans. In a fluid at rest, the pressure is constant at any given point regardless of the direction. This is known as Pascal's principle, which states that the pressure in a fluid acts equally in all directions at a specific point.
2. What factors affect the pressure variation in a fluid at rest?
Ans. The pressure variation in a fluid at rest is affected by the density of the fluid and the height of the fluid column. The pressure in a fluid increases with an increase in density and height.
3. Does the shape of the container affect pressure variation in a fluid at rest?
Ans. The shape of the container does not affect the pressure variation in a fluid at rest. As long as the fluid is at rest, the pressure is constant at any given point within the fluid, regardless of the container's shape.
4. How is pressure measured in a fluid at rest?
Ans. Pressure in a fluid at rest can be measured using a manometer, which is a device that measures the pressure difference between two points within the fluid. The height difference of the fluid levels in the manometer corresponds to the pressure difference.
5. Can pressure vary in a fluid at rest if it is not in equilibrium?
Ans. In a fluid at rest that is not in equilibrium, pressure can vary depending on factors such as acceleration or gravitational forces acting on the fluid. In this case, the pressure distribution within the fluid may not be constant at all points.
