Question 1.
Define uniform flow in your own words.
Show hintHide hint
Think about it as no changes occurring in the flow pattern.
Question 2.
What does it mean if a flow is non-uniform?
Show hintHide hint
Consider how this affects fluid dynamics near solid boundaries.
3Question 3.
What defines uniform flow?
- Velocity changes with time and space
- Velocity is constant across space
- Velocity changes only with time
Show hintHide hint
Consider how velocity behaves in different scenarios.
4Question 4.
True or False: Non-uniform flow indicates that the fluid properties are the same at all points.
- True
- False
Show hintHide hint
Think about the impact of varying conditions.
Question 5.
Given a velocity field represented by u = 2xy, v = 3y², find the equation of the streamline passing through the point (2, 3).
Show hintHide hint
Start by relating the y-component to the x-component using the equations separately.
Question 6.
For a scenario where a river’s flow is uniform for a section and non-uniform near the edges, analyze how the turbulence might differ based on viscosity and solid boundaries.
Show hintHide hint
Consider how boundary layers form near surfaces.
