Fluid Dynamics Flashcards
Pressure is caused by the _ of the column above that point.
Weight
Buoyant force is equal to the weight of the _ _.
Displaced fluid
If there is an increase in pressure on one side of a fluid, then _ points throughout the fluid will have that pressure.
All
Depth increases _ because it has to counteract the weight to make it in equilibrium or else the liquid would accelerate downward.
Pressure
Forces caused by fluid pressure are _ to the surface.
Perpendicular
Absolute pressure is 0 in a _.
Vacuum
Width and shape do not affect _.
Pressure
Different heights in a tube can be due to _ differences.
Pressure
A hydraulic jack has a small area and a large area and the pressure as the _, so larger force on larger area.
Same
_ is created because the upward pressure on the block is greater than the downward pressure due to depth.
Buoyant force
Use density and volume of the _ _ in calculations.
Fluid displaced
The volume of the liquid displaced is not of the object, only the _ _.
Submerged portion
Volume flow rate is _.
Constant
When flow is faster, _ is lower.
Pressure
The velocity at the top of a container can be assumed to equal _.
Zero
