The continuity equation of fluid mechanics utilises the principle of conservation of _________________?
Correct answer: B. Mass
- A. Momentum
- B. Mass
- C. Energy
- D. Both B. & C.
Explanation
The continuity equation is obtained by applying conservation of mass to fluid flowing through a control volume. Energy conservation belongs to the Bernoulli or mechanical-energy equation, while momentum conservation gives the momentum equation.
