Question
What is the basis of Bernoulli’s principle?
Advertisements
Solution
The basis of Bernoulli's principle is the law of conservation of energy.
This law says that in a steady flow, the speed of a fluid in a narrow region increases, but the internal pressure of a fluid in the same narrow region decreases. The work done per unit volume of a fluid by the surrounding fluid is equal to the sum of the changes in kinetic and potential energies per unit volume that occur during the flow.
