Cylindrical velocity
WebFeb 20, 2024 · The shaded cylinder has a volume V = Ad, which flows past the point P in a time t. Dividing both sides of this relationship by t gives V t = Ad t. We note that Q = V\t and the average speed is ¯ v = d / t. Thus the equation becomes Q = A¯ v. Figure 12.1.2 shows an incompressible fluid flowing along a pipe of decreasing radius.
