What are the two forms of drag that act on a body as it traverses through a fluid medium? Which form of drag is dominant in streamlined and blunt bodies? What is the mechanism that causes drag?

Solution

The drag force exerted by the fluid on the cylindrical body in the direction of flow depends upon the Reynolds number of the flow , with increase in reynolds number thw flow pattern becomes unsymmetrical withnrespect to the axis perpendicular to the direction of flow .
