ok dude, you have gone far enough being stupid.
drag can be calculated experimentally.
and the drag coefficient can be obtained from von karmen integral if you have the velocity profile, which can be accurately assumed from the flow conditions.
and the drag coefficient can also be calculated using the drag formula, provided you have the value of drag.

and phusllllesssssee, DO NOT say that drag coefficient changes with velocity, infact no coefficient does so, drag coeff entirely depends on geometry relative to flow.
think yourself dude, if the drag coefficient changes, what's its use??

next time you comment anything, make sure you are fully prepared

and sorry for last time, i didnt mean that stupid thing in any offensive manner and neither now

Dear i<3math :

In fluid dynamics drag is the resistance offered by the fluid to the motion of a body. Drag is a force that depends on velocity, coefficient of drag(which is different for different geometries), density of the medium(fluid) in which the body is moving and the maximum cross-sectional area of the body exposed to the fluid. Drag can be calculated using standard formula

compare the formula given to you -->R = (1/2)DA(rho)v**2

with the standard formula -->drag = [Cd*density*(velocity^2)*plan area]/2

you can find that the resistance force R = Drag(D) [in Newton],

Cd = Coefficient of drag = D

rho = density (for air it is 1.225 Kg/m**3) & V = velocity (m/s)

velocity here is the relative velocity between the body and the fluid

I think now you can calculate the drag force on the given body
