The cross-section area of the pipe shown in Fig is at the wider portions and at the constriction. The rate of flow of water through the pipe is . Find the velocities at the wide and the narrow portions.

A force is applied on a cube of side , Another force, double the magnitude of the previous force is applied on a cube of . What is the ratio of pressure on the first cube To the pressure on the second cube ?

When the area decreases-

Which among the following is an assumption of Hagen-Poiseuille equation?

Shear stress is caused due to

How solids are different from fluids?

What is fluid and how it is different from a solid?

Explain with an example how shear stress is cause due to tangential force.

Describe the effect of nature of liquid and temperature on surface tension?

The _____ of a fluid is defined as the ratio of the shearing stress between adjacent layers of fluid to the rate of change of velocity perpendicular to the direction of motion.

The velocity of water in river is near the surface. If the river is deep, then the shearing stress between the surface layer and the bottom layer is (coefficient of viscosity of water, )

The shear stress of a fluid depends on:

How shear stress for fluids is different from solids?

An ideal fluid can not experience shearing stress.

Which one of given is not a property of the liquid?

Which one of the given option is not the property of the solid?
