Gas Turbine & Psychrometric chart

AI Thread Summary
Understanding the Psychrometric chart is crucial for analyzing air quality in gas turbines, particularly concerning dew point, humidity, and pressure effects. An increase in air pressure can lead to condensation of water vapor, posing risks of moisture-related issues like corrosion in compressors. Resources such as the provided links can help clarify these concepts and the physical implications of psychrometry. Modern engines are designed to handle significant moisture, including rain, without severe issues. Mastering the fundamentals of psychrometry is essential for ensuring engine integrity and performance.

Hi Everyone,
So I seem to have many problems understanding the Psychrometric chart and its physical meaning. First of all, I would be so thankful if you could introduce me a source which can be useful to physically and fundamentally understand the dew point, effect of pressure, humidity... and better to say Psychrometric chart.

Actually I was reading some articles about gas turbine, and I have started to think about the air input, its quality, and the risk of moisture and consequently corrosion. There should be a risk of water drops in compressor if the vapor in inlet air condenses... It is here where my problem with psychometry starts... so if the compressor increases the pressure of air, it means that the probability of condensation increases or decreases?

I hope you can help me understand the fundamental of psychometry, I feel embarrassed not to understand it well :)

Modern engines can ingest huge amounts of rain without too many problems .

The engine integrity tests carried out are very rigorous and include rain , hail , cowling ice , frozen chickens and deliberately broken fan blades .

Check out this site for learning about the Psychrometric Chart. Yes an increase in pressure can cause water vapor to condense.

Edit: Here's the link http://www.powerknot.com/how-to-read-and-use-a-psychrometric-chart.html
I failed at embedding it.

Which site is that? There's no link apparent.
 
Regarding water vapour formation and condensation - anyone remember the cloud chamber experiments from school days ?
 
Thnaks everyone!
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
