When plumbing a house, a number of devices include contractions from the pipe behind the wall to the outlet of the water, such as a faucet. Consider that steady incompressible flow occurs a contraction. The entrance diameter is 0.6 in and exit diameter is 0.3 in. At a volumetric flow rate of 0.2 ft3/s, what is the difference in the Reynolds number at the exit if the fluid is water at 70 ̊F
