Can you explain and comment on the Newtonian viscosity equation?

AI Thread Summary
The Newtonian viscosity equation describes the relationship between the force of friction in a fluid and the velocity gradient, with viscosity as the proportionality factor. This relationship is supported by meticulous experimental evidence demonstrating its accuracy. While there are more complex aspects to discuss regarding fluid dynamics, the fundamental principle remains that viscosity quantifies how a fluid resists flow. Understanding this equation is crucial for applications in various fields, including engineering and physics. Further exploration of the topic can provide deeper insights into fluid behavior.

Could anyone explain me and comment the Newtonian viscosity equaton?
 
Physics news on Phys.org
I assume you mean, why is the force of friction in a fluid proportional to the velocity gradient in it? (the proportionality factor being the viscosity)

The simplest answer is that meticulous experiments showed that that was, indeed, a very good approximation.

There's a lot more to say about this, of course, but I'll let this be enough for today
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
