Pneumatic piston cylinder design

AI Thread Summary
The discussion focuses on designing and simulating a pneumatic piston cylinder, specifically calculating the force profile of the piston over time. It emphasizes that the force is dependent on fluid pressure, which varies as the piston moves. Participants suggest using a polytropic process to model gas pressure changes during the piston stroke. There is a request for assistance in developing differential equations with time as a variable. The conversation highlights the need for simulation software suitable for pneumatic systems.

Freinds,
I have to design and simmulate a pneumatic piston cylinder, and want to calculate force profile of piston with time. please help me in this regard, also please tell me any simmulation software simmulating pneumatic piston cylinder.

The force will be a function of the fluid pressure (air in this case). The pressure will change as the piston strokes (in or out). Use a polytropic process to model the gas pressure.

yes ofcourse force will be a function of the fluid pressure. but i have to developed differential equations with time as a dependent variable. please help me in this regard.
 

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

Thread 'Technical Analysis on Titan Sub (Titanic Sub)'

TL;DR Summary: Heard in the news about using sonar to locate the sub Hello : After the sinking of the ship near the Greek shores , carrying of alot of people , there was another accident that include 5 tourists and a submarine visiting the titanic , which went missing Some technical notes captured my attention, that there us few sonar devices are hearing sounds repeated every 30 seconds , but they are not able to locate the source Is it possible that the sound waves are reflecting from...
