 Properties of Air at 1 atm Pressure Properties of air For ideal gases, the properties cρ, k, µ, and Pr are independent of pressure. The properties ρ, ν, and α at a pressure P (in atm) other than 1 atm are determined by multiplying the values of ρ at the given temperature by P and by dividing v and α by P.
 Specific Gravity Table Chart and Equation Specific gravity of various materials, gasses and liquids. In the International System of Units (SI Units), the density of water is 1.00 g/cm3 at the standard temperature.
 Speed of Sound Table Chart Speed of Sound table chart including Speed of Sound at a known temperature and density of air, Speed of Sound vs Density of Air.
 Air Density Equations and Calculator The following is a Air Density and Specific Weight Equations and Calculator. Variables required include Temperature, Humidity, Barometer and altitude
 Water - Density Viscosity Specific Weight Water - Density Viscosity Specific Weight, Dynamic and Kinematic Viscosity of Water in Imperial Units (BG units). Density and Weight of Water at Known Temperature
 Leidenfrost effect The Leidenfrost effect is a phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer keeping that liquid from boiling rapidly.
 Description of a Simple Vector - Physics Vectors are simple straight lines used to illustrate the direction and magnitude of certain quantities.
 Resultant Vector Physics A resultant is a single vector which represents the combined effect of two or more othervectors (called components). The components can be determined either graphicallyor by using trigonometry.
 Scalar Quantities - Physics Most of the physical quantities encountered in physics are either scalar or vector quantities.
 Vector Identification - Physics In textbooks, vector quantities are often represented by simply using a boldfaced letter (A, B, C, R).
