AI Thread Summary
The discussion focuses on the challenges of accurately calculating relative humidity (RH) of moist air at temperatures above 100°C using the Magnus relation, which is effective only up to that point with necessary corrections. Users are seeking alternative methods or resources, such as psychrometric charts, but most available charts are limited to 55°C. Suggestions include using wet bulb and dry bulb thermometers along with charts for practical calculations. The conversation highlights the need for more comprehensive tools or methods for engineers dealing with higher temperature ranges. Accurate RH calculations are crucial for various applications in engineering and environmental science.

Calculate RH of moist air at higher temp ranges accurately?

Hey there :)
Im using the Magnus relation for calculating the RH of air (sat pressure the RH) only to find it works good only for temperature ranges upto 100°C (with corrections to original Magnus relation!)
Does anybody know a better method to calculate RH accurately (or thru Psychrometric charts-all charts I found have ranges upto 55°C only)??
Any help is welcome!
Thnx in advance :biggrin:

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
