Chapter 3: Elementary Fluid Dynamics Flashcards
1
Q
What is a steady flow?
A
asd
2
Q
What is a streamline?
A
Lines tangent to the velocity vector at every point along the line.
3
Q
What is Bernoulli’s equation? and what are its requierments?
A
An equation of kinetic energy per volume at different points along a streamline.
1/2rhou^2+p+rhogz=constant
The following assumptions need to be satisfied
- Flow is steady (at least quasi-steady)
- Constant density (incomp)
- Points taken at the same streamline.
- No viscous forces/Asssume inviscid.
