Newton’s law of viscosity for a fluid states that the shear stress is
A real fluid is any fluid which
When subjected to shear force, a fluid
An Ideal Fluid
Ideal Fluid: A fluid, which is incompressible and is having no viscosity is known as ideai fluid. Ideal fluid is only an imaginary fluid as all the fluids, which exists have some viscosity.
Which one of the following is defined as force per unit length?
Surface tension is defined as line force per unit length.
Newton’s law of viscosity depends upon the
According to Newtons law of viscosity
The fluid which obey’s the Newton’s Saw of viscosity
The fluid which obeys the Newton’s law of viscosity is known as Newtonion fluid e.g.: Air, water, Kerosene.
The General relationship between shear stress (τ) and velocity Gradient for a fluid can be written as
Then the fluid known as
In the expression:
If n < 1, B = 0
then it is known as pseudo plastic
Surface tension is due to
Surface tension a line force caused by cohesion of fluid particle at the surface, the property of cohesion enables a liquid to resist tensile stress.
Which one of the following is correct dimension of surface tension?
