SUMMARY

The discussion focuses on optimizing indoor clothes drying through evaporation, emphasizing key factors such as heat, airflow, humidity, and light. The user seeks clarification on the appropriate equations for calculating mass loss rate due to evaporation, referencing Irving Langmuir's equation and the Penman/Shuttleworth equation. The user is currently utilizing the equation gh = Θ A (xs - x) from Engineering Toolbox for their calculations. The consensus indicates that understanding these equations is crucial for effective indoor drying strategies.

PREREQUISITES
  • Understanding of evaporation principles and factors affecting it
  • Familiarity with mass transfer coefficients
  • Knowledge of thermodynamic equations related to vapor pressure
  • Basic grasp of airflow dynamics in indoor environments
NEXT STEPS
  • Research the Penman/Shuttleworth equation for evaporation rates
  • Study the application of mass transfer coefficients in drying processes
  • Explore the impact of airflow on evaporation efficiency
  • Investigate the role of temperature and humidity in indoor drying scenarios
USEFUL FOR

Engineers, physicists, and anyone involved in indoor drying processes, including laundry services and HVAC professionals, will benefit from this discussion.

I am trying to find the most efficient way to dry clothes indoors with different evaporation factors
1. Heat/Temperature
2. Airflow
3. Humidity
4. Light (Electromagnetic energy)

But I am not sure what equation to use.
(mass loss rate)/(unit area) = (vapor pressure - ambient partial pressure)*sqrt( (molecular weight)/(2*pi*R*T) by Irving Langmuir?
Penman/Shuttleworth equation?
Mass transfer coefficient?
