Question | Answer |
Principle stating that the buoyant force exerted on an immersed body is equal to the weight of the fluid displaced. | Archimedes' principle |
Principle stating that the total energy (represented by kinetic energy, potential energy, and pressure) for a confined ideal fluid flowing through a pipe is conserved at all locations within the pipe. | Bernoulli's principle |
Law stating that the volume of a confined gas is inversely proportional to the pressure it exerts, if the temperature remains constant. | Boyle's law |
Law stating that the volume of a confined gas at constant pressure is directly proportional to its Kelvin temperature. | Charles's law |
The study of how fluid moves and how forces and energy are transmitted through fluids. Subdivided into hydrostatics and hydrodynamics. | fluid mechanics |
A property of all fluids in which pressure is exerted equally in all directions at any point in the fluid. | fluid pressure |
The SI unit of pressure equal to one Newton of force over a square meter (N/m x m). | pascal |
Principle stating that changes in pressure on the surface of a confined fluid are distributed equally throughout the fluid and at all points on the fluid's container. | Pascal's principle |
The force pushing directly on a given surface. | pressure |
The tendency of a fluid flowing past a curved surface to follow the surface. | Coanda effect |
The area of physics dealing with the transfer of forces and work done by confine fluids according to Pascal's principle. | hydraulics |
Water pressure due only to depth in a body of water. | hydrostatic pressure |
An instrument that measures atmospheric pressure. It consists of sealed glass tube of mercury containing a vacuum. The meniscus of the column indicates air pressure on a calibrated scale. | mercury barometer |
The ratio of a substance's density to water's density; a unit less quantity numerically equal to the density of the substance. Also called relative density. | specific gravity |
