SUMMARY

The discussion focuses on calculating the amount of condensate released when 90°F air at 80% relative humidity (RH) is cooled to 40°F. The user determined that approximately 0.02192 ounces of condensate water is produced per cubic foot of air by referencing a specific chart from Process Heating. This calculation involves subtracting the water content of 40°F air at 100% RH from that of 90°F air at 80% RH. The method and results are confirmed as a valid approach to solving the problem.

PREREQUISITES
  • Understanding of relative humidity and its impact on air properties
  • Familiarity with psychrometric charts and their application
  • Basic knowledge of thermodynamics related to air temperature and moisture
  • Ability to perform calculations involving water content in air
NEXT STEPS
  • Research psychrometric charts for various temperatures and humidity levels
  • Learn about the properties of air at different temperatures and relative humidity
  • Explore the equations governing condensation and dew point calculations
  • Investigate tools for calculating moisture content in air, such as HVAC software
USEFUL FOR

This discussion is beneficial for HVAC engineers, meteorologists, and anyone involved in projects related to air conditioning, humidity control, or condensation calculations.

Per cubic foot of hot 90F humid 80%RH air, how much water is released when that air temp is dropped to 40F?

Thank you for any comments.
