Consider steady flow through the duct with circular cross section illustrated below.

Use mass conservation to find \(U_{2}\) in terms of \(U_{1}\) assuming \(D_{2} / D_{1}=2\) and:

a. The flow is steady, incompressible, and uniform across the entrance and exit of the duct.

b. The flow is steady, incompressible, with a parabolic distribution across the duct exit.

c. The flow is steady, compressible, and uniform across the entrance and exit of the duct with \(T_{2} / T_{1}=5\) and \(P_{2} / P_{1}=2\).
