Answer to Question 1

ANS: A
Transitional flow is a mixture of laminar and turbulent flows that typically occur where tubes di-vide. See Figure 1-15. Restricted flow occurs when narrowing or constrictions occur along the length of a tube. Laminar and turbulent flows can become restricted if an obstruction is encoun-tered along the length of a tube.

Answer to Question 2

ANS: B
With turbulent flow, the movement of fluid molecules becomes chaotic and the orderly pattern of concentric layers seen with laminar flow is lost. Transitional flow is the mixture of laminar and turbulent flows. If the movement of fluid is said to be streamlined, it is laminar. Fluid mechanics does not describe the flow of fluids as being random.
