Radius Surface Surface tension Tension

AI Thread Summary

To estimate the radius of each droplet produced by a sprayer, equate the volume of the liquid exiting the sprayer to the total volume of the smaller droplets formed. Given a liquid density 'p' and a sprayer hole radius 'r', the volume of the large drop can be calculated. This volume is then divided by 'n', the number of equal-sized droplets, to find the volume of each droplet. Using the volume formula for a sphere, the radius of each droplet can be derived. This method effectively allows for the estimation of droplet size based on the initial conditions of the sprayer.

Nuclear on the Rocks

i have a question on surface tension.
if i had a a sprayer which squirted a liquid of density p through a hole of radius 'r', following which the liquid breaks into 'n' equal-sized droplets.can i estimate the radius of each droplet??

Yes equate the volume of large drop to the volume of n small drops.

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
