Question

Which of the following is the best definition of viscosity?
	A.	the tendency of a fluid to support a floating object
	B.	the ability of a fluid to transmitted a force
	C.	the thickness of a fluid, or its resistance to flow

C. Is the right answer, viscosity is how a liquid resist flow. It has units of  $$\frac{ N*S }{ m^2 }$$ for the coefficient viscosity.

One addition: the units are newton-seconds per meter.

shamim · Answer

The above unit is wrong!!!

shamim · Answer

U know the equation 
F=eta*A*dv/dy
Here eta is viscocity

shamim · Answer

Can u tell me the unit of eta frm my equation

shamim · Answer

Eta=F*dy/A.dv

shamim · Answer

Unit of viscocity=N.m/(m^2.m.s^-1)=N.s/m^2
