1.6. Viscosity and Its Effects

Try these first

1. 1.

   What is uniform flow?

   Hint

   Think about how water flows smoothly in a straight river.

2. 2.

   Define viscosity.

   Hint

   Consider how honey flows compared to water.

3. 3.

   What is the definition of uniform flow?

   • Velocity changes with space
   • Velocity remains constant across space
   • Velocity changes with time

   Hint

   Remember the smooth flow of water in a calm stream.

4. 4.

   Is viscosity the same as density?

   • True
   • False

   Hint

   Think about how thick a fluid feels compared to how heavy it is.

5. 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?

   Hint

   Apply the principles of continuity and Bernoulli's theorem to analyze.

6. 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).

   Hint

   Set up your equations carefully, integrating one at a time!
