Question
Here's a nice graphic of a Venturi tube, indicating three regions.
Assume that there is laminar flow throughout the tube.
(A) Which quantity is uniform (constant) throughout the tube?
(Click to select)the volume flow ratethe pressurethe velocitythe area
(B) Consider the fluid pressure inside the tube.
In which region is the pressure going to be the greatest? (Click to select)ABC
In which region is the pressure going to be the least? (Click to select)ABC
(C) Consider the velocity of the fluid inside the tube.
In which region is the speed going to be the greatest? (Click to select)ABC
In which region is the speed going to be the least? (Click to select)ABC
Explanation / Answer
A)from the equation of continuity we can say volume flow will be constant.
C )velocity is inversely proportional to the cross-sectional area
at C area is greatest so at C velocity will be Least.
at B area is least so at B velocity will be greatest.
B) In venturi tube kinetic energy convert into pressure energy & vice-versa.
so at the point where velocity is maximum pressure will be minimum
at C velocity is Least so at C pressure will be greatest.
at B velocity is greatest so at B Pressure will Least.
