I just have one quick question on using direct calorimeters on humans, and it might be a dumb question but its got me a bit confused. From my understanding the calorimeter will measure the change in temperature of water from the heat that a person's body gives off. I understand that when...

Thanks for the reply. I think my main confusion arose when thinking about the effects of compliance of a vessel on local blood pressure in comparison to what bernoulli's equation would predict. If a vessel had high compliance, then when some volume of blood is injected into it, it would...

Okay, I have read all the threads on this site that I could find about Bernoulli's equation and blood pressure, but I am still really confused, and the more I think about it the more confused I get. I get that bernoulli's doesn't take frictional losses into account, but at a short section of...

This might be a stupid question, but it has me kind of confused. In diffusion, molecules will flow from high concentration to low concentration, and the explanation typically given is that in the laws of thermodynamics there is a net increase in entropy over time. But I am trying to think of...

Alright that makes sense. Thanks for the help.

Thanks for the reply. Alright so just for clarification: If the hand was holding the mass up at equilibrium, then the force of the mass on the hand would be equal to mg, correct? But because the hand is moving downwards, the force of the mass on the hand is <mg. So in an FBD the forces...

This is going to be a very elementary question, but I am having a hard time wrapping my head around it for whatever reason. In static equilibrium, like a book on a table, I have no problem seeing that the force exerted on the table by the book is equal and opposite to the force exerted on the...
