If the cross-sectional area of a pipe carrying water is reduced by half while the velocity remains constant, how does the discharge (Q) change?
6. If the cross-sectional area of a pipe carrying water is reduced by half while the velocity remains constant, how does the discharge (Q) change?
- Q remains constant
- Q doubles
- Q halves
- Q quadruples
Answer: C) Q halves
Explanation:
According to the continuity equation, Q = A × V. If area (A) is halved and velocity (V) remains constant, the discharge (Q) will also halve.
