Fluid Dynamics

The study of properties of fluids in motion is called

The dimensions of coefficient of viscosity is:

The equation 𝐹 = 6𝜋𝜂𝑟𝑣 is called:

An object moving through a fluid experience a retarding force called:

When weight of an object falling freely becomes equal to the drag force, then the body will move with:

The maximum constant velocity of an object falling vertically downward is called:

When the body reaches its terminal velocity, the acceleration of the body becomes

As the water falls from tap, its speed increases and cross sectional area:

If radius of droplet becomes half then its terminal velocity will be:

Turbulent flow is
