An argument on the drag coefficient of a sphere results in the expression C=C 0 [1+δ 0 /(R) 1/2 ] 2 where R is Reynolds number, C 0 δ 0 2 =24 , and δ 0 =9.06 This expression is in remarkable agreement with experiment for a wide range of R , i.e., 0≤R5000 .DOI...

The famous drag model by (Schiller and Naumann, 1935) correlates the drag coefficient for a single and rigid sphere by dividing relative bubble Reynolds Reb number into two ranges. For Reb≤1000, CD is a function of relative Reynolds number only and for Reb>1000, CD has a constant value ...
cd = drag coefficient ρ = density of fluid (1.2 kg/m3 for air at NTP) v = flow velocity (m/s) A = characteristic frontal area of the body (m2) The drag coefficient is a function of several parameters like shape of the body, Reynolds Number for the flow, Froude number, Mach Numbe...
Especially the later part of the movement gets relevantly influenced by air drag deceleration. We theoretically estimate an average sphere drag coefficient for the relevant part of the movement of falling spheres. The results are verified by examining the drag coefficient from expe...
The drag coefficient has a minimum value at same normal fluid Reynolds number, Re[sub n] ≈ 2.5 x 10[sup 5] for each temperature. This is in reasonable agreement with the minimum in the classical sphere drag coefficient curve at approximately Re = 3 x 10[sup 5]. The drag crisis is ...
