Question

Hydraulic system works on the basis of ____________

(a) Archimedes principle

(b) Pascal’s principle

(c) Bernoulli’s Principle

(d) Newton’s second law of motion

This question was addressed to me in unit test.

I would like to ask this question from Fluid Statics and Fluid Dynamics topic in chapter Fluid Flow Theory & Applications of Food Processing Unit Operations

Answer 1

Correct answer is (b) Pascal’s principle

To explain I would say: Hydraulic system works on the basis of Pascal’s principle. This principle states that when pressure is applied to a closed system of fluid, the pressure is transmitted to every part of the fluid and also to the walls of the container in which fluid is enclosed.
