AI Thread Summary
The discussion focuses on calculating the energy required to destroy an iron hollow cylinder when gunpowder explodes inside it. The user has inner and outer dimensions of the cylinder and is using the enthalpy of combustion to estimate energy. There is uncertainty regarding the conversion of energy to thermal energy and the specific energy needed for destruction. Factors such as the material properties of the cylinder also play a role in the calculations. Accurate energy consumption estimates depend on these variables and require further analysis.

When some gun powder explode in a iron hollow cylinder , how much energy consume to destroy that cylinder?
We have inner and outer diameter and height .
I calculate all of energy by enthalpy of combustion , I don`t know how much convert to thermal energy and how much consume to destroy .

I guess it also depends partly on the cylinder.
 
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...
