Q. I. Bernoulli's equation ideally applies to non-viscous fluids.
II. Fluid must be compressible in Bernoulli's theorem.
III. Bernoulli's equation does not hold for non-steady flow. Which of the following statement(s) is/are correct?

Mechanical Properties of Fluids

Solution:

Statements I and III are correct but II is incorrect and it can be corrected as,
A restriction on application of Bernoulli's theorem is that the fluids must be incompressible as the elastic energy of the fluid is also not taken into consideration.
