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
 
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...
