Question

 Hydraulic ram is used for lifting heavy vehicles or items. What is the principle behind the application of hydraulic ram?
1. Pascal's law
2. Bernoulli's law
3.  Newton's law
4. Navier-Stoke's law

Answer 1

Correct Answer - Option 1 : Pascal's law

Explanation:

1. The hydraulic ram is a pump that raises water without any external power for its operation.
2. One essential requirement for the satisfactory operation of a hydraulic ram is the availability of a large quantity of water with a small positive head or height. This large quantity of water at a small height is sufficient to lift a small quantity of water to a greater height.
3. The hydraulic system works on the principle of Pascal’s law which says that the pressure in an enclosed fluid is uniform in all directions.
