Advanced Standard Temperature and Pressure Calculator
Since gases do not have definite volumes, scientists have agreed upon standard temperatures and pressures at which gas volumes can be compared. 1) Before 1982, the International Union of Pure and Appl
Arrhenius Equation Calculator
The equation was first proposed by the Dutch chemist J. H. van 't Hoff in 1884; five years later in 1889, the Swedish chemist Svante Arrhenius provided a physical justification and interpretation for
Boyle's Law Calculator - Calculates Volume and Pressure
Boyle's law is an experimental gas law that relates to the pressure and volume of a fixed mass of a gas approaching an ideal gas when the temperature is held constant. This law is also known as the
Critical Oil Flow Rate Calculator
Mayer & Garder were the first to proposed this concept for determining the Critical oil flow rate for a gas-oil isotropic reservoir with the perforated interval at the lower bottom of the oil zone.
Dilution Of Solutions Calculator
A solution is a homogeneous mixture of two or more substances, which may be solids, liquids, gases, or a combination of these. A solvent is capable of dissolving another substance. A dilution is a pro
Half-Life Calculator
The Half Life Time of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value. The term Half Life Time was coined in 1907. The Half L
Ideal Gas State Equation
Ideal Gas State Equation was first stated by Benoît Paul Émile Clapeyron in 1834. It determines the relationship between its pressure, volume and temperature. The Equation of State of an Ideal Gas, wh
Liquid Phase Diffusion Coefficient Calculator
Diffusion can be defined as mixing of two or more substances or the net motion of a substance from an area of high concentration to an area of low concentration. Diffusion Coefficient can be defined a
NPSH Calculator
This calculator is used to calculate the Net Positive Suction Head available (NPSHa) for each pump in the system.
Radioactive Decay Calculator
Radioactivity was first discovered in 1896 by the French Scientist Henri Becquerel while working on phosphorescent materials. In 1898, Marie Curie discovered that pitchblend, a uranium ore, emits more
Souders-Brown Equation Calculator
The Souders-Brown equation has been the tool for obtaining the maximum allowable vapor velocity in vapor-liquid separation vessels. A vapor-liquid separator (or knockout) drum is a vessel into which a
Specific Heat and Density Calculator
It is the amount of heat that is required to change the temperature of a mass unit of any substanceonly by one degree. To find specific heat capacity we can say that it is a measure of the total energ

Spectra Library
The spectral library was assembled to facilitate laboratory and field spectroscopy and remote sensing for identifying and mapping minerals, vegetation, and manmade materials.
Standard Temperature and Pressure Calculator
Standard Temperature and Pressure is defined as air at 0 C (273.15 K, 32 F) and 1 atm (101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 29.92 in Hg, 760 torr, 33.95 Ft.H2O, 407.2 In.W.G, 2116.8 Lbs./Sq.
