AI Thread Summary
Compressor work in steady-flow systems is directly related to the specific heat of the fluid, particularly in air compressors where a factor of 1.4 is often referenced for efficiency. When air is compressed, it heats up before being transferred to an air receiver chamber, where it cools and experiences a slight pressure drop, indicating energy loss. This cooling process signifies a waste of input energy, emphasizing the importance of understanding specific heat in compressor design. Further inquiries can help clarify the relationship between specific heat and compressor efficiency. Understanding these principles is crucial for optimizing compressor performance.

Why is the compressor work (steady-flow) proportional to the specific heat of the fluid?

Welcome to PF, sorry about the delay.
Maybe you are referring to the ratio or factor of 1.4 in air compressor efficiency.
The air is compressed which also heats it, then passed to an air receiver chamber where it cools, so the pressure drops slightly. That cooling represents a waste of input energy.
See; http://en.wikipedia.org/wiki/Heat_capacity_ratio
Then ask more specific questions as needed.
 

Thread 'Bubble formation in 4 mm gap vessel'

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...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

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...
