Examples of plasma are stars; they are very hot gases that electrons are stripped away
from their nucleus.
When you heat a gas the volume changes greatly in comparison to solids and liquids.
Does it make sense that streamlines to cross one another? If they can it means that some
of the river is going in different directions, so the answer is no. The lines show the motion
of the streamlines ideally, which is how we are going to look at it
There is no theory to this day about turbulent flow. Very unpredictable, use of
supercomputers can give an idea of it but not close enough. That is why people test things
in wind tunnels.
Irrotational & Rotational Flow
Vortices are the circles.
Rake through water: turbulent flow leaves vortices after.
Flux is velocity x area
Density of fluid x volume x area x amount of time
Because delta t is the same in both, it is cancelled out in the equation
