What is vapor pressure deficit and why is it important in agriculture?

The vapor pressure is a measure of the presure (force per unit area) exerted by a gas above a liquid in a sealed container. Volatility is the property of a liquid fuel that defines its evaporation characteristics. Reid vapor pressure is a common measure of and generic term for ... The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of ... Enthalpies of fusion and melting points obtained using Differential Scanning Calorimetry (DSC) were used to obtain sub-cooled liquid vapour pressures. They have ... Temperature and Vapor or Saturation Pressure for some common Fluids · water : 100 oC (212 oF) · ethyl alcohol : 78.5 oC (173 oF) ... element State. A. B. C. D T(melt). K. 'Li'.

An equation valid between the critical point and 0°K is where is the vapor pressure constant, 5.31733, and the subscript designates use of the scale throughout ... The vapour pressure of a pure compound can be calculated from the Clausius-Clapeyron equation applying Trouton's rule. Trouton's rule says that ∆hVap = ∆hVapTb ... ... liquid vapour pressure to a solid vapour pressure for solids. For compounds with no experimental vapour pressure data in the experimental database, the ... Vaporization Rate (Liquid to Vapor), 272:1. Combustion Data : Limits of ... Vapor Pressure at 0°F, 28 PSI. Vapor Pressure at 70° F, 122 PSI. Vapor Pressure ...
