Direct Heat Transfer Between a Liquid And a Gas

Click For Summary
SUMMARY

The discussion centers on calculating the heat transfer rate between a liquid (water) and a gas in a chamber with no heat transfer to the walls. The key factors include the temperature difference between the liquid and gas, as well as the pressure conditions. To determine the heat transfer rate, one must apply the principles of convective heat transfer, utilizing equations such as Newton's Law of Cooling and considering the specific heat capacities of both phases. The discussion highlights the importance of understanding these thermodynamic principles for accurate calculations.

PREREQUISITES
  • Understanding of convective heat transfer principles
  • Familiarity with Newton's Law of Cooling
  • Knowledge of specific heat capacities of water and gas
  • Basic thermodynamics concepts related to pressure and temperature
NEXT STEPS
  • Research convective heat transfer coefficients for liquid-gas interfaces
  • Study Newton's Law of Cooling in detail
  • Explore the impact of pressure on heat transfer rates
  • Learn about specific heat capacities of common gases and liquids
USEFUL FOR

Engineers, thermodynamics students, and researchers involved in heat transfer analysis, particularly those working with liquid-gas systems in controlled environments.

Hey guys,

I was trying to find the answer to this question but could not seem to find anything. I am trying to figure out how to calculate heat transfer rate between a liquid and a gas. Say the the liquid is water in a chamber (with no heat transfer to the walls). The gas is the residual space above the liquid, meaning that the contact surface is the surface of the water. Given the gas and the liquid are at a certain pressure, but the temperature of the gas and the liquid differ. How can I find the heat transfer rate for this problem? Much thanks for help!

Regards,
Bob
