Question 1.
Define a velocity field in fluid mechanics.
Show hintHide hint
Think about how we describe motion in different directions.
Question 2.
What is a pressure gradient?
Show hintHide hint
Consider how changes in pressure might influence fluid behavior.
3Question 3.
What is a velocity field?
- A method of pressure analysis
- A representation of fluid velocity
- A visual model of fluid motion
Show hintHide hint
It concerns how fast fluid moves.
4Question 4.
Incompressible flow assumes density is constant. (True/False)
- True
- False
Show hintHide hint
Consider the impact of Mach number.
Question 5.
Given the velocity field of a fluid in a pipe, calculate the pressure drop across a distance of 10 meters if the velocity varies linearly from 2 m/s to 5 m/s.
Show hintHide hint
Think about how pressure influences velocity and vice versa.
Question 6.
In a scenario where a gas flows through a narrowing pipe section, explain how the pressure and density change, especially when the Mach number exceeds 0.3.
Show hintHide hint
Remember the relationship between pressure, velocity, and density in compressible flow.
