How to calculate the saturated water content in nitrogen
Thread Content
A stream of nitrogen is introduced into the water, and upon being expelled, it is already saturated with water. I want to know how to calculate manually the water content in nitrogen gas
It should be similar to air; check the humidity at the corresponding temperature
Can it be calculated using Raoult’s law? The water vapor pressure is equal to the saturated vapor pressure of water multiplied by the mole fraction of water in the solution. Since the molar fraction of water in the solution is approximately 1, the partial pressure of water is approximately equal to its saturated vapor pressure. The total pressure is known; the total pressure minus the vapor pressure of water gives the vapor pressure of nitrogen. Once the partial pressures of the two are known, their molar ratio can be determined, and thus the water content can also be known
