Calculating Air Temp Increase from Atmospheric to 3 Bar Pressure

AI Thread Summary
To calculate the temperature increase of air when pressurized from atmospheric pressure to 3 bar using a piston-type air pump, one can apply principles from the adiabatic process. The relevant formula for an isentropic process is T2/T1 = (p2/p1)^(gamma-1/gamma), where gamma is 1.4 for air. The initial temperature T1 is typically the normal atmospheric temperature. The discussion emphasizes the importance of determining whether the process is isentropic or polytropic, as this affects the calculations. Understanding these principles is crucial for accurate temperature predictions during air compression.

How to calculate the raise in temperature of air when it's pressurized by a piston type air pump from atmospheric pressure to 3 bar(gauge pressure) ?
 
Engineering news on Phys.org
one can read wikipedia on "Adiabatic process", there are expressions involving both pressures, temperatures and gamma = 1.4 for air
 
it depends upon the process.whether its isentropic or polytropic.If its isentropic then the formula wouls be

T2\T1=(p2/p1)^(gamma-1\gamaa0.gamma=1.4
 
sorry its gamma -1\gamma.t1 may be normal temp
 
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.

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?'
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...
