When tubes have one or more branches, the flow becomes:
a. transitional. c. turbulent.
b. restricted. d. laminar.
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.
