AI Thread Summary
In an axial compressor, wheel speed typically refers to the linear tip speed rather than the rotational speed, which is measured in radians per second. The axial velocity being constant at U = 50 m/s indicates a specific linear speed rather than a direct correlation to rotational speed. The discussion emphasizes the need for clarity on these terms, as they can be easily confused. Understanding the distinction between linear and rotational speed is crucial for accurate analysis in compressor performance. This clarification is essential for anyone working with axial compressors.

Plz I need ur urgent Help : Wheel speed

what is the wheel speed in an axial compressor ?
for example when we say that the axial velocity remains constant and equal to the wheel speed of U = 50 m/s?
Does this refer to the rotational speed , or just a value for the axial velocity ?

Please I need your urgent Help as soon as possible .

Thanks In advance

Wow , many views but no answer ??
I don't hink it is a difficukt question although I didnt know it :)
 
That will, most likely, be the linear tip speed. It can't be rotational velocity with units of m/s.

The wheel speed of a compressor is generally the rotational speed (if memory serves me correctly). However, like Fred pointed out, it is normally not in m/s but rather radians/s. Are you taking it out of context perhaps?

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
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'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
