hi federico,

my cd value is coming 0.78 where in research paper it is around 1.2 for  Re=2x10^4.

this value coming when i am giving reference value as follows

Area=0.1 (as diameter)
density=1.225
Depth=1
Length=1
Velocity=2.93
Viscosity=1.7894e-05

can you give any suggestion so I can reduce my error?
