Final answer:
The formula for flow rate is Q = Av, where Q is the flow rate, A is the cross-sectional area, and v is the average velocity.
Step-by-step explanation:
The formula for flow rate is Q = Av, where Q is the flow rate, A is the cross-sectional area, and v is the average velocity.
For incompressible fluids, the flow rate at various points is constant, as stated by the equation of continuity.
Flow rate is directly proportional to both the magnitude of the average velocity and the size of the conduit.
