Given information:
- A cylindrical vessel has its height equal to its diameter.
- The vessel is filled with liquid.
- The vessel is moved horizontally with an acceleration equal to the acceleration due to gravity.
To find:
The ratio of the liquid left in the vessel to the liquid at static equilibrium condition.
Solution:
1. Analysis of the situation:
- When the vessel is at static equilibrium, the liquid inside is at rest and experiences a downward force due to gravity.
- When the vessel is moved horizontally with an acceleration equal to the acceleration due to gravity, the liquid inside experiences a pseudo force in the opposite direction.
- This pseudo force acts on the liquid and tends to push it towards the side opposite to the direction of acceleration.
2. Effect of acceleration on the liquid:
- Due to the acceleration, the liquid inside the vessel moves towards the side opposite to the direction of acceleration.
- As the liquid moves, it forms a parabolic shape, with the highest point being at the center of the vessel.
- The height of the parabolic shape is determined by the acceleration and the diameter of the vessel.
3. Calculation of the height of the parabolic shape:
- Let the diameter of the vessel be D, and the acceleration be a.
- The height of the parabolic shape can be given by the equation: h = (a/2g) * D^2
- where h is the height of the parabolic shape, a is the acceleration, and g is the acceleration due to gravity.
- Since the height of the vessel is equal to its diameter, the height of the parabolic shape can be written as h = (a/2g) * h^2
4. Calculation of the ratio of the liquid left:
- The volume of the liquid left in the vessel can be calculated by subtracting the volume of the parabolic shape from the total volume of the vessel.
- The volume of the parabolic shape can be calculated using the formula for the volume of a paraboloid: V = (π/2) * h^2 * (3D - h)
- The total volume of the vessel can be calculated using the formula for the volume of a cylinder: V_total = π * (h/2)^2 * h
5. Calculation of the ratio:
- The ratio of the liquid left to the liquid at static equilibrium condition can be given by the formula: ratio = (V_total - V) / V_total
6. Substituting the values:
- Substituting the values of V and V_total in the ratio formula, we get: ratio = [π * (h/2)^2 * h - (π/2) * h^2 * (3D - h)] / [π * (h/2)^2 * h]
7. Simplifying the ratio:
- Simplifying the ratio formula, we get: ratio = (4h - 3D) / (4h)
8. Substituting the value of h:
- Substituting the value of h from the equation h = (a/2g) * D^2, we get: ratio = (2aD^2 - 3D) / (2aD^
