Difficulty: Easy
Choose an option
-
AThere is no energy loss in the flowing liquid
-
BVelocity is uniform over each cross-section considered
-
CNo body force other than gravity acts on the fluid
-
DAll of the above
Answer
Correct Answer: All of the above
Explanation
Concept/Approach
- Bernoulli's equation is derived for inviscid (no losses), steady, incompressible flow along a streamline, with only gravity as body force and using one-dimensional (section-averaged) velocity at the cross-section.
Final AnswerAll of the above
