Week 5: Static Pressure Flashcards
1
Q
Fluid
A
Any liquid or gas that continuously deforms under a shear stress.
2
Q
How does pressure act in relation to a surface in static pressure?
A
Perpendicular.
3
Q
What is pressure caused by in fluid mechanics?
A
Pressure is caused by the weight of the fluid above.
4
Q
What does pressure not depend on?
A
Pressure does not depend on area or shape.
5
Q
Pressure Equation
A
P = ρhg
where ρ = fluid density
h = depth
g = acceleration due to gravity
6
Q
How can the total pressure of two layers of fluid be calculated?
A
Adding up the different pressures.
7
Q
Atmospheric Pressure
A
Pressure that accounts for the air above it (Patm).
