Bernoulli's equation for fluid flow is derived following certain assumptions. Out of the assumptions listed below, which set of assumptions is used in derivation of Bernoulli's equation? A. Fluid flow is frictionless & irrotational. B. Fluid flow is steady. C. Fluid flow is uniform & turbulent. D. Fluid is compressible. E. Fluid is incompressible ?
Correct answer: C. A, B, E
- A. A, C, D
- B. B, D, E
- C. A, B, E
- D. A, D, E
Explanation
The usual Bernoulli derivation assumes steady, frictionless or inviscid, incompressible flow, with irrotational flow allowing the equation to apply generally. Thus the valid set is A, B, and E.
