Energy released by condensing steam back to liquid water

Click For Summary
SUMMARY

The energy lost from not condensing 19 kg of steam back to liquid water is equivalent to the energy required to vaporize that amount of water, calculated using the latent heat of water at 2260 kJ/kg. Given that it took 42.9 MJ to vaporize the water, the total energy loss from not condensing the steam is also 42.9 MJ. This conclusion assumes a 100% efficient process with pure water at the boiling point, although real-world conditions may vary.

PREREQUISITES
  • Understanding of latent heat concepts
  • Basic knowledge of thermodynamics
  • Familiarity with energy conversion units (MJ to kJ)
  • Ability to perform energy calculations
NEXT STEPS
  • Research the principles of latent heat and its applications in thermodynamics
  • Learn about energy efficiency in phase change processes
  • Explore real-world applications of steam condensation in power generation
  • Investigate methods to improve the efficiency of vaporization and condensation systems
USEFUL FOR

Students studying thermodynamics, engineers working with steam systems, and anyone interested in energy efficiency in phase change processes.

Homework Statement


vaporized 19 kg of water and did not capture and condense it. It took 42.9 MJ to vaporize the water, how much energy did I lose from not condensing the steam?

Homework Equations


Latent Heat of Water = 2260kJ/kg

The Attempt at a Solution


Would the energy lost to not capturing the condensation be the equivalent to the energy needed to vaporize the water?

If your initial water was completely pure, directly at the boiling point and your process was 100% efficient, probably. I doubt that for realistic setups, especially the last part. Anyway, you don't have to care about that to find the answer.
