Answer:
B. A large cross sectional area,
Explanation:
To permit a large flow of water in a pipe, the cross sectional area of the pipe must be significantly large. According to the flow rate equation:
V =
Where:
Q is the Volume flow rate and it is the volume of fluid that flows through the pipe
V is the velocity of the fluid in the pipe
A is the cross sectional area of the pipe.
From the equation, we see that for a larger amount of water to flow in a pipe, the cross-sectional area must be very large. In short, Q varies directly as A.
