hey hi....
here it is..
>>>The first point of view for the cause of drag is the skin friction. As the solid object moves through the fluid, All the parts of the object comes in contact with the fluid. If the surface of the solid is very rough and the fluid is a high viscous fluid, there will be a huge amount of drag.
>>>On the other hand, when a smooth surface and a fluid of low viscosity comes in contact (with the shape being the same), a relatively low drag force is generated....
Another cause may be mentioned to be the aerodynamic shape of the solid object This type of drag occurs due to the pressure difference on different parts of the solid body.
hope this helps.....
