Show hintHide hint
Think about forces acting throughout the mass of the fluid.
3Question 3.
What does a control volume represent in fluid mechanics?
- A fluid property
- A defined space in fluid flow analysis

Remember the definitions of both force types.
Question 5.
A fluid flows due to gravity along a channel. Discuss the control volume approach to analyze the forces acting on the fluid.
Show hintHide hint
Draw a diagram of the control volume and consider forces acting in different directions.
Question 6.
Describe how assuming incompressible and isothermal flow simplifies the Navier-Stokes equations and give an example.
