When a vacuum is pulled on the water with a 29.4 in.Hg,What is vapor created for each pound of water removed in cubic feet?
To determine the amount of vapor created for each pound of water removed in cubic feet when a vacuum of 29.4 inHg is applied, you need to use the vapor pressure table for water.
Here's the step-by-step process:
1. Determine the boiling point of water at the given pressure of 29.4 inHg. The boiling point of water varies with pressure. You can use a vapor pressure table or a chart to find the corresponding boiling point for this pressure.
2. Once you have determined the boiling point, subtract it from the ambient temperature. This difference will give you the temperature difference between the boiling point and the surrounding temperature.
3. Use the temperature difference to find the specific volume of water vapor for every pound removed. Specific volume is given in cubic feet per pound (ft³/lb) and represents the volume of a substance per unit mass.
4. Multiply the specific volume by the mass of water removed (in pounds). This will give you the volume of vapor created for each pound of water removed in cubic feet.
Note: The specific volume will change with the pressure and temperature conditions. Ensure you use the correct values from the vapor pressure table or any other relevant data source.
By following these steps, you can determine the vapor created for each pound of water removed in cubic feet when a vacuum of 29.4 inHg is applied.
