Heat Exchange Between Air & Water: 1 Cubic Meter Each

Click For Summary
SUMMARY

The discussion focuses on the heat exchange process between 1 cubic meter of water at 23 degrees Celsius and 1 cubic meter of air at 20 degrees Celsius, with a surface area of 1 square meter for heat transfer. It is established that the temperatures will equalize within a few minutes due to thermal diffusion, although the heat will never fully balance. Key factors influencing this process include surface tension of the water and vapor pressure of the humid air.

PREREQUISITES
  • Understanding of thermal diffusion principles
  • Knowledge of heat transfer mechanisms
  • Familiarity with surface tension concepts
  • Basic grasp of vapor pressure in humid air
NEXT STEPS
  • Research thermal diffusion equations and calculations
  • Explore heat transfer methods in fluid systems
  • Study the effects of surface tension on heat exchange
  • Investigate vapor pressure dynamics in humid environments
USEFUL FOR

Students and professionals in thermodynamics, environmental scientists, and engineers working on heat exchange systems.

If i have let's say have 1 cubic meter of water at a temperature of 23 degree, in a closest system connected to a 1 cubic meter of air of 20 degree, how long time does it take for the heat to balance out, the surface between the two a 1 square meter.

The "heat" will never balance. The temperatures will equalize in a few minutes, depending upon the surface tension of the water and the vapor pressure of the overlying humid air. This is essentially a problem in diffusion.
