Related to this QuestionWhat is vapor pressure and how it relate to temperature. w Determine the vapor pressure of ammonia at 20 C given that H v a p = 23.35 K j / m o l and vapor pressure at 78.0 C is 5.98 k P
Vapor pressure and Temperature:At a given temperature, every liquid exit in equilibrium with its vapour. The pressure exerted by its vapor is known as vapor pressure. Vapor pressure increases with temperature. The relationship between vapor pressure and temperature is given by Clausius-Clapeyron ...

Formula to calculate outgassing using conductance method Where, P1 and P2 are pressure of the pumps C is the conductance A is the internal surface area of the chamber to be tested Material evaluation check for PCB outgassing Outgassing affects the performance of the boards that are implemented ...
What is the effect of pressure on dew point? Air compression increases water vapor pressure and thus dew point. It is important to take this into consideration if you are bleeding the air to atmosphere before taking a measurement. The dew point at the measurement point will be different from...
Depending on the method used to estimate reference evapotranspiration (ETO) in the simulation model, vapour pressure and wind speed may also be needed. Although measured data are always preferable to propagated or derived weather data, daily data for the other variables required for crop modelling ...
