2. Blood flows through a tapered vessel at 2 l/min, as shown in Figure 2. Assume the flow is inviscid and steady, density is 1 g/cm, and gravity is negligible. Points 1 and 2 are 7 cm apart and the diameter changes linearly with axial position, x. Let x = 0 at point 1. a. Determine V2. Hint: you may assume that the velocity does not vary with radial position because the change in vessel diameter is gradual. Likewise, you...
