Question

What is viscocity and define coefficient of viscocity?

Answer 1

The viscocity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.

The degree to which a fluid resists flow under an applied force, measured by the tangential friction force per unit area divided by the velocity gradient under conditions of streamline flow is called the coefficient of viscocity.

Answer 2

HLO MATE HERE IS UR ANSWER.

❤. VISCOCITY ❤

⭐. The property of resistance of flow is called viscosity.

⭐. Viscosity of a liquid is a measure of its frictional resistance to the flow of liquid.

⭐. If viscosity increases then flow of liquid decreases.

SI units : N s m^-2 or Pa.s

CGS Units : poise ; 1 poise = 1 g cm^-1 s^-1

❤. COEFFICIANT OF VISCOCITY ❤

⭐. coefficient of viscosity may be defined as the force of friction required to maintain unit velocity gradient between two parallel layers of unit area of contact.

It is denoted by n

F= nA du/dx

Si units : N.sm^-2 = pa.S

CGS units ; poise.
