Pressure coefficient — The pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field in fluid dynamics. The pressure coefficient is used in aerodynamics and hydrodynamics. Every point in a fluid flow field has its own … Wikipedia
Density of air — The density of air, ρ (Greek: rho) (air density), is the mass per unit volume of Earth s atmosphere, and is a useful value in aeronautics and other sciences. Air density decreases with increasing altitude, as does air pressure. It also changes… … Wikipedia
Pressure — This article is about pressure in the physical sciences. For other uses, see Pressure (disambiguation). Pressure as exerted by particle collisions inside a closed container … Wikipedia
Pressure altitude — In aviation, pressure altitude is the indicated altitude when an altimeter is set to an agreed baseline pressure setting. This setting 101,325 Pa, equivalent to 1013.25 millibar (or hectopascals), or 29.92 inches Hg is equivalent to the air… … Wikipedia
Blood pressure — For information about high blood pressure, see Hypertension. Blood pressure Diagnostics A sphygmomanometer, a device used for measuring arterial pressure. MeSH … Wikipedia
Particle density — The particle density or true density of a particulate solid or powder, is the density of the particles that make up the powder, in contrast to the bulk density, which measures the average density of a large volume of the powder in a specific… … Wikipedia
Sound pressure — Sound measurements Sound pressure p, SPL Particle velocity v, SVL Particle displacement ξ Sound intensity I, SIL Sound power Pac Sound power level SWL Sound energy Sound energy d … Wikipedia
Standard conditions for temperature and pressure — Not to be confused with Standard state. In chemistry, standard condition for temperature and pressure (informally abbreviated as STP) are standard sets of conditions for experimental measurements, to allow comparisons to be made between different … Wikipedia
Diagonal relationship — A diagonal relationship is said to exist between certain pairs of diagonally adjacent elements in the second and third periods of the periodic table. These pairs (lithium (Li) and Mg, Be and Al, boron (B) and silicon (Si) etc.) exhibit similar… … Wikipedia
