8 wrz 2014 · The formula W=-nRTln (Vfinal/Vinitial) is suggested as a possible solution. The conversation also touches on the use of additional physical property information and the possibility of using an equation of state for more accurate results.
The ratio of gas volume to water volume at the same temperature and pressure, or gas–water ratio, is a sensitive indicator of the behavior of a gas reservoir connected to a water source, such as an aquifer or injected water.
21 wrz 2022 · Dalton's law can be used to calculate the amount of the desired gas by subtracting the contribution of the water vapor: \[\begin{array}{ll} P_\text{Total} = P_g + P_{H_2O} & P_g \: \text{is the pressure of the desired gas} \\ P_g = P_{Total} - P_{H_2O} & \end{array}\nonumber \]
With the ideal gas law, we can use the relationship between the amounts of gases (in moles) and their volumes (in liters) to calculate the stoichiometry of reactions involving gases, if the pressure and temperature are known. This is important for several reasons.
This is a mathematical statement of Henry’s law: The quantity of an ideal gas that dissolves in a definite volume of liquid is directly proportional to the pressure of the gas.
10 lut 2015 · Convert the provided temperature and pressure values to appropriate units (K and atm, respectively), and then use the molar amount of hydrogen gas and the ideal gas equation to calculate the volume of gas:
If liquid displacement is possible, calculate the volumetric expansion of gas through the control valve down to 1.1 or 1.16 x MAWP. Note that typically the flow will be limited by and/or choked through the flow limiting element and that flow calculated earlier (see Step 1) is based on an isentropic flow path.
