Show hintHide hint
Think about simplifying equations.
Question 2.
Define body forces and provide an example.
Show hintHide hint
Consider how forces act on a fluid's entire mass.
3Question 3.
What is the purpose of a stream function?
- To simplify equations

Show hintHide hint
Consider how different forces can interact with fluid.
Question 5.
Given a fluid with a uniform density in a vertical tube, describe how both body and surface forces interact under gravitational force, using stress tensors.
Show hintHide hint
Sketch the fluid and identify forces acting on both fluid and boundary.
Question 6.
Derive and explain the relationship between the stream function and mass flow rate across two streamlines in terms of fluid density.
Show hintHide hint
Consider how stream functions represent conservation principles visually.
