Show hintHide hint
Think about how water flows smoothly in a straight river.
Question 2.
Define viscosity.
Show hintHide hint
Consider how honey flows compared to water.
3Question 3.
What is the definition of uniform flow?
- Velocity changes with space
- Velocity remains constant across space
- Velocity changes with time
Show hintHide hint
Remember the smooth flow of water in a calm stream.
4Question 4.
Is viscosity the same as density?
- True
- False
Show hintHide hint
Think about how thick a fluid feels compared to how heavy it is.
Question 5.
A pipe has water flowing through it uniformly at a speed of 3 m/s. If the diameter of the pipe changes, how would that affect the major properties of flow?
Show hintHide hint
Apply the principles of continuity and Bernoulli's theorem to analyze.
Question 6.
In a 2D flow, the velocity components are given as u = 3y and v = -2x. Find the equation of the streamline that passes through the point (1,2).
