Question

Which of the following is NOT an assumption taken in the Bernoulli theorem?

• A. The fluid is inviscid.
• B. The flow is rotational.
• C. The flow is incompressible.
• D. The flow is steady.

Answer 1

Answer:

B. The flow is rotational.

Bernoulli's Equation states that in a steady, ideal flow of an incompressible fluid, the total energy at any point of the fluid is constant. The assumptions taken in the Bernoulli theorem are that the fluid is ideal, steady, incompressible, and irreversible, with no external force acting on the liquid except gravity. The option that is NOT an assumption taken in the Bernoulli theorem is "The flow is rotational."
