What Is the Resistivity of Pure Steam?

Click For Summary
SUMMARY

The discussion centers on the resistivity of pure steam and its relationship with temperature. It is established that the resistivity of water decreases as temperature increases, although a specific mathematical relationship remains elusive. Additionally, while some sources claim that steam has infinite resistance, this is inaccurate; a more precise value in the range of megaohms or gigaohms is sought. The moderator emphasizes that questions of this nature should be directed to appropriate forums for better assistance.

PREREQUISITES
  • Understanding of electrical resistivity concepts
  • Basic knowledge of thermodynamics, particularly the behavior of water and steam
  • Familiarity with measurement units such as ohms, megaohms, and gigaohms
  • Experience with scientific research methodologies
NEXT STEPS
  • Research the mathematical relationship between temperature and resistivity of water
  • Investigate the resistivity values of various states of water and steam
  • Explore the principles of electrical conductivity in gases
  • Review scientific literature on the properties of steam in thermodynamic contexts
USEFUL FOR

Researchers, physicists, and engineers involved in steam quality assessment and those studying the electrical properties of fluids.

I am working on a Project that involves determination of Quality of Steam. In that I have few queries, so please help if possible:

1. Is there any mathematical relationship between Resistivity of water and temperature? because i am not able to find one, but since i am working on this project, so by doing practical I found that: Resistivity of water decreases with increase in temperature, but I am not able to find any mathematical relationship?

2.What is the resistivity of pure steam?
I read on the net, that steam has infinite resistance, but infinite does not exist so there must be some value ( may be in Mega ohm, giga ohm, etc); I am looking for that value?

Thanks.
