1.5. Basics of fluid mechanics -II (contd.)

Try these first

1. 1.

   What does Bernoulli's equation relate?

   Hint

   Think about the conservation of energy in fluid flow.

2. 2.

   What is an extensive property?

   Hint

   Examples include mass and volume.

3. 3.

   What does Bernoulli's principle state about fluid flow?

   • Higher speed leads to higher pressure
   • Higher speed leads to lower pressure
   • Speed has no effect on pressure

   Hint

   Think of how fluids behave in a constricted space.

4. 4.

   True or False: The Reynolds transport theorem relates changes in a system to a control volume.

   • True
   • False

   Hint

   Consider how properties flow across control surfaces.

5. 5.

   In a tapered pipe where the diameter decreases, how would you predict the change in fluid velocity and pressure if the flow rate is constant?

   Hint

   Apply continuity and Bernoulli in conjunction.

6. 6.

   How can you apply the Reynolds transport theorem in a scenario where the flow properties are changing rapidly?

   Hint

   Map the changes in properties across control surfaces.
