For steady ideal fluid flow, the Bernoulli's equation states that the_________________?
Correct answer: C. Energy is constant along a stream line, but may vary across stream lines
- A. Velocity is constant along a stream line
- B. Energy is constant throughout the fluid
- C. Energy is constant along a stream line, but may vary across stream lines
- D. None of these
Explanation
Bernoulli's equation expresses conservation of mechanical energy along a streamline for steady, ideal, inviscid flow. Different streamlines may have different total-energy constants, so energy need not be uniform throughout the fluid.
