Click For Summary
SUMMARY

This discussion centers on calculating the energy lost in a t-shirt cannon system, particularly focusing on the energy within the pump that propels the t-shirt. Participants emphasize the importance of demonstrating prior effort before receiving assistance, highlighting the forum's rules against posting without showing work. The conversation also touches on the misinterpretation of comments, stressing the need for clarity in communication within scientific discussions.

PREREQUISITES
  • Understanding of basic physics principles related to energy transfer
  • Familiarity with the mechanics of pneumatic systems
  • Knowledge of energy conservation laws
  • Ability to perform calculations involving work and energy
NEXT STEPS
  • Research the principles of energy conservation in pneumatic systems
  • Learn about the calculations involved in measuring work done by pumps
  • Explore the dynamics of projectile motion as it relates to t-shirt cannons
  • Investigate common methods for measuring energy loss in mechanical systems
USEFUL FOR

This discussion is beneficial for physics students, engineers interested in mechanical systems, and anyone involved in designing or analyzing pneumatic devices like t-shirt cannons.

Homework Statement
Find the energy lost of the system of a manually pumped T-shirt cannon (with a bike pump). Consider loss of energy to friction and loss of pressure.
Relevant Equations
mgh
1/2mv^2
PV = nRT
W = Fd
I don’t even know where to start. I especially don’t know how I would find the energy inside of the pump that would then be released to shoot a T-shirt.

How is it that you have been given a homework problem that you don't even have any idea where to start on?

The rules of this forum are that you have to show some work on your own before we can give you any help.

because it isn’t a homework. It’s a study being conducted by me.
So why did you post it in the homework section where everyone would assume it's homework, particularly since you did not say it wasn't?

But thanks for being so curt and rude anyway. I’ll ask others.
I think you must be accustomed to social media where it's OK to assume that any negative statement is an attack. Your interpretation of my statement is completely wrong. This is a science form and the rules are as I stated. Statements of fact on this forum should not be interpreted as an attack, just a statement of fact.

If you show no effort, you get no help. Well, actually, not everyone follows the rules so someone might jump in and help but you'd be better off showing some work.
