6.2.1. Flow Classifications

Try these first

1. 1.

   Define steady flow.

   Hint

   Think about whether velocities change or remain constant.

2. 2.

   Explain incompressible flow.

   Hint

   Consider how liquids behave under pressure.

3. 3.

   What is steady flow?

   • A flow varying with time
   • A flow with constant parameters
   • A flow without momentum

   Hint

   Does the flow change or stay the same?

4. 4.

   True or False: Incompressible flow assumes that density can change.

   • True
   • False

   Hint

   Recall the definition of incompressible flow.

5. 5.

   Given a steady flow in a tube with varying diameters, derive an expression for velocity change using Bernoulli's equation.

   Hint

   Use conservation of energy concepts.

6. 6.

   Calculate the flow rate using a venturimeter with a diameter of 2 cm at point 1 and 1 cm at point 2 if the difference in pressure measures 100 Pa.

   Hint

   Consider the relationship between diameter changes and velocity.
