In fluid flow, for the equation of continuity A1v1 = A2v2. If the velocity of the fluid at one end is doubled, then what will be the cross-sectional area at this end?
Correct answer: B. Half
- A. Double
- B. Half
- C. (Half)2
- D. (Double)2
Explanation
Half: This is the correct answer. According to the equation of continuity (A1v1 = A2v2), if the velocity of the fluid at one end is doubled, the cross-sectional area at that end will be halved to maintain the constant product.
