What is velocity gradient ?

The relative velocity between two layers of fluid, separated by 0.1 mm is 2 cm//s . Calculate the velocity gradient.

The S.I. unit and dimensions of velocity gradient is streamline flow is

The relative velocity between two layers of fluid, separated by 0.4 mm is 8 cm//s . What will be the velocity gradient?

The velocity gradient of certain liquid is 5s^(-1). If thickness of liquid layer is 2.5 cm, then velocity of flow of liquid will be

What is potential gradient? How it is measured? Explain.

The relative velocity of two parallel layers of water is 8 cm/sec. If the perpendicular distance between the layers is 0.1 cm, then velocity gradient will be

An incompressible liquid flows through a uniform cross section tube with velocity 12 cm/s. the thickness of liquid layer is 0.8 cm then velocity of gradient of flow is

The tangential force or viscous force on any layer of the liquid is directly proportional to the velcoity gradient dupsilon//dx. Then the direction of velcoity gradient is
