Estimating Tracheal Volume Flow: Physics Activity for Adults | Fun Activity

AI Thread Summary
The discussion revolves around estimating the volume flow of air through an adult's trachea during inhalation, with a focus on a fun physics activity. Participants are encouraged to measure their inhalation time using a stopwatch to calculate the flow rate in cubic meters per second. One user shared their result of 0.3 m^3/s and questioned whether it was accurate, seeking averages from others. The diameter of the adult human trachea is noted as 25mm, which is relevant for calculations. Overall, the activity combines practical measurement with physics concepts, fostering engagement and curiosity.

Fun physics activity!

Homework Statement


Under the conditions of normal activity an adult inhales about 1.1l of air during each inhalation. Using a stopwtch, determien the time for one of your own inhalations (avg several to get two significant digits) and hence estimate the volume flow in m^3/s through your trachea during inhalation. the diameter of adult human trachea is 25mm


Homework Equations


q=m^3/s


The Attempt at a Solution



What is a proper or normal average for this kind of thing? I think my answer might be off lol ! i just want to get a good average, tell me what yours is! its kinda fun isn't it!?

I got 0.3m^3/s does it make sense?
 


What time are you using for your inhalations?
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
