yes, viscous force is present in air. it is proportional to the velocity and area of the body and acts in the opposite direction of velocity.

spring mass dashpot (viscous damper) with these you can model any vibrational system via mx''+cx'+kx=f(x) where f(x) is the exciting force
Yes electrical and electronic engineering discipline is eligible for air force common admission test.
Centrifugal force of the fan results in an increase in static force. The blades of the axial flow fans force air to move parallel to them.
Viscous drag
A buoyant force is not present in air because air is less dense than objects that float in it, so there is no upward force pushing objects up like in water.

Force that resists motion is frictional force, viscous drag
Viscous fluids are difficult to pour or flow easily because they have high resistance to deformation and flow. This resistance is due to the strong intermolecular forces present in viscous fluids, which make it harder for the molecules to move past each other. As a result, viscous fluids flow slowly and require more force to pour compared to less viscous fluids.

The friction force exerted by fluids is typically referred to as viscous drag. This force arises due to the friction between the moving object and the fluid it is moving through. Viscous drag depends on the velocity of the object and the properties of the fluid.
When a body falls through a viscous medium such as air or water, the resistance force increases as the speed of the body increases. This leads to a terminal velocity being reached when the upward force of resistance cancels out the downward force of gravity, resulting in a constant velocity. The experiment involves measuring this terminal velocity to study the effects of viscosity on the motion of the falling body.
The force caused by friction between the air and the surface of an object is known as air resistance or drag. This force opposes the motion of the object through the air, slowing it down. It becomes more significant at higher speeds or when the object has a larger surface area.

Viscous friction is a type of frictional force that occurs when an object moves through a fluid, such as air or water. It is caused by the resistance between the object and the fluid, resulting in a loss of kinetic energy and a decrease in the object's speed. Viscous friction is proportional to the velocity of the object and the viscosity of the fluid it is moving through.
