what is the coefficient of viscocity?
pavan49:
The degree to which a fluid resists flow under an applied force, expressed as the ratio of the shearing stress to the velocity gradient. The coefficient of viscosity of liquids decreases as temperature increases because the bonds between molecules are weakened.
thanks bro

the degree to which fluid resist to flow under an applied force express as the ratio of shearing strees to the velocity gradiant
what is the formula
fd/av
where f is force ,d -distance,a-area,v-velocity
thanks a lot
its my pleasure

The ratio of shearing stress to velocity gradient is called as coefficient of viscosity.
Its common symbol is etta.
Its SI unit is Pa sec.
It is also described as the degree to which a liquid resists flow under an applied force.
