We can use the following formulas to calculate these properties:
Creating a psychrometric chart in Excel is a powerful way for HVAC engineers and students to automate thermodynamics calculations and visualize air property changes. While manual charts are standard, an Excel-based version allows for instant updates based on altitude or changing input parameters like dry-bulb temperature and relative humidity.

Note that this is just a basic example, and you may want to add more functionality, error checking, and formatting to make the chart more useful. We can use the following formulas to calculate
Psychrometric charts have numerous applications in HVAC, including: including: For RH=10%: =0.62198*(0.1*B2)/(101325 - 0.1*B2)
For RH=10%: =0.62198*(0.1*B2)/(101325 - 0.1*B2)
