hydraulic machines

machines which use fluid to transmit or increase force


fluid mechanics

The study of fluid movement and forces


Bernoulli's principle

States that the pressure of a fluid decreases as its speed increases


fluids

liquid or gas phases of matter


Boyle's law

the volume of a dry gas is inversely proportional to the pressure it exerts, if the temperature remains constant


pressure

the force pushingdirectly on a given surface


Archimedes' principle

the buoyant force exerted on a body in a fluid is equal to the weight of the fluid displaced


pascal (Pa)

unit of pressure equal to one newton of force over a square meter (NN/m(2))


Pascal's principle

changes in pressure in a confined fluid are distributed equally in all directions throughout the fluid


Charles's law

the volume of a gas at a constant pressure is directly proportional to its Kelvin temperature


barometer

a device used to measure atmospheric pressure
