When a solid particle moves through fluid then three force acting on the solid particle along with. these three forces are :
Gravitational force is due to the weight of the particle acting downward. buoyancy force due to the weight of the displaced fluid by the solid body.buoyancy force acting upwards exactly opposite to the gravitational force. drag force is the force which acts due to the movement of solid through the fluid or movement of fluid over the solids.the direction of drag force is opposite to the solid movement.
The drag force consists of two. these are friction drag and pressure drag.
total drag =friction drag + pressure drag
total drag is given by
- Gravitational force
- Buoyancy force
- Drag force
