Question

to permit a large water flow , the pipe must have, A.enough strength,B.a large cross sectional area, C.enough length to conduct the flow or ,D. a sufficient drop

Answer 1

a large cross-sectional area

Step-by-step explanation:

Answer 2

B. A large cross sectional area,

Step-by-step 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 =
`(Q)/(A)`

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.
