that makes sense thanks a lot!

ok , thanks a lot !

??

it does ? so we have a change in pressure between two points in the hose, so the velocity is not constant ?

so the final answer is that viscosity is the same for a given fluid at any velocity .

Hello, I am currently studiying Bernoulli's equation and I have trubble understanding something , say we have a horizontal hose (no change in altitude of pressure ) Bernoulli's equation state that an ideal fluid can flow thought the hose with the same velocity , does an ideal fluid need a...

hello, I read in a lecture paper about fluid mechanics that velocity is not related to viscosity, i found this odd and i think it is an error , can someone confirm that?

nice! thanks, man.

thanks, interesting information but do you have the final answer?

no, it is the first lines that come off when I typed "which nervous system is responsible for vasodilation"

Hello, I have some trouble understanding the role of the sympathetic nervous system in vasoconstriction and vasodilatation of blood vessels, I searched and found contradicting resources, does anyone have the right answer?

I found the first one by typing surface tension formula on google , and the second :

thank you very much for your reply, it's just that when I heard " the more oxygen is bound to hemoglobin, the easier it is for more oxygen to bind" i thought directly to an exponential curve, in reality, a sigmoid curve resembles an exponential curve in the beginning until saturation (the...
