P=F/A (force/area)
Pressure in a fluid is exerted _______ in all directions.
Equally
Changes of pressure on the surface of a confined fluid are exerted equally throughout the fluid and at all points on the fluid's container.
Pascal's principle
Objects weigh less in water or other fluids than they do when they are not immersed.
Buoyancy
Liquids and gases are considered fluids.
True
Indicated by a mercury barometer
Absolute pressure
Compares density of a substance with the density of water
Specific Gravity

Coanda effect
Water pressure due to depth.
Fluid pressure
Hydraulic machines are applications of ___________ principles.
Pascal's
Measures fluid pressures in mechanical systems and pipes.
Gauges
Wheelbarrows are which type of lever?
2nd class
Liquids like water are incompressible but gases were highly compressible.
Bernoulli's principle
An immersed object is lifted or buoyed up by a force equal to the weight of the fluid displaced.
Archimedes principle
Increasing pressure, _________ volume.
More compact than a mercury barometer
Aneroid Barometer
Term that describes any surface designed to deflect air or create a force as it moves through the air.
Airfoil
