Does the viscosity of air change with change in the degree of humidity

Click For Summary
SUMMARY

The viscosity of air is directly affected by changes in humidity at room temperature. Increased humidity results in lower air viscosity, which is supported by empirical data presented in a referenced article. The article provides level curves illustrating the relationship between air viscosity and humidity, confirming that as moisture content rises, air becomes less viscous.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with the concept of viscosity
  • Basic knowledge of humidity and its measurement
  • Awareness of temperature's effect on gas properties
NEXT STEPS
  • Research the impact of humidity on the viscosity of other gases
  • Explore the mathematical modeling of viscosity in fluids
  • Investigate the role of temperature in gas viscosity changes
  • Learn about experimental methods for measuring air viscosity
USEFUL FOR

Researchers in atmospheric science, engineers in fluid mechanics, and anyone studying the physical properties of gases will benefit from this discussion.

Yes!

Here is an extract from an article, detailing air viscosity as a function of humidity, by means of level curves for the temperature:
