The pressure drop resulting from a constriction in a tube can be restored by which of the follow-ing?
 
  a. An increase in flow rate
  b. A postconstriction increase in radius
  c. The addition of another entrainment port
  d. A further decrease in the radius of the tube

Question 2

Following the Bernoulli principle, when a fluid approaches a constriction in a tube, there will be a(n) ____ in acceleration and a(n) ____ in lateral pressure.
 
  a. Decrease, decrease c. Increase, decrease
  b. Decrease, increase d. Increase, increase

Answer to Question 1

ANS: B
This question involves the Venturi principle, which states that the pressure drop caused by fluid flowing through a tubular constriction can be restored to preconstriction values by allowing for a gradual dilation in the tube.

Answer to Question 2

ANS: C
As fluid approaches a constriction in a tube, the flow of the liquid will accelerate (increase) as it enters the constriction, which in turn causes a decrease in lateral-wall pressure.
