The Viscosity of Fluid: a) - resistance to flow b) - a measure of internal shear c) - depends upon shear forces and velocity profile d) - answers 1 and 3

a) Resistance to flow

Explanation:

Viscosity of fluid:

Resistance to flow is called as viscosity of fluid. It is also know as fluid friction. It try to stop the flow of fluid. Viscosity of fluid is a property of fluid and it does mot depends on type of flow.

If fluid viscosity is high it means that it have very low flow ability. And opposite to viscosity is called fluidity. If fluidity is high then it means that it have low viscosity.

Viscosity are of two type

1. Dynamic viscosity

2. Kinematic viscosity
