WebSep 12, 2024 · The precise relationship between flow rate Q and average speed v is Q = Av, where A is the cross-sectional area and v is the average speed. The relationship tells us that flow rate is directly proportional to both the average speed of the fluid and the cross-sectional area of a river, pipe, or other conduit. WebSo, our equation of motion is: F c = m a c, F N + m g = m v 2 r. To find the critical speed, we set the normal force to zero, as we did with the tension before, and we arrive at the same equation for the critical speed: 0 + m g = m v c 2 r, v c = g r. So the critical speed of … philadelphia field office secret service
