    Drag Force at very very high Renolds Number ?

    as in let's take an example for a sphere of radius 0.1 m moking with the speed of 100 m/sec Renolds = pv/viscosity which gives 10^7 so what wud be the drag force calculating expression for this situation

    Drag Force at very very high Renolds Number ?

    What is the expression for Drag Force at very very High Renolds Number flow (>10^6) as we know the expression for drag force between Re1 and Re10^5 = 0.5kpAv^2 but this isn't valid aft 10^5 .. so ...

    Does Spinning A Sphere Increase Drag in Air?

    If a sphere is moving through air. Will it have more drag if it is spinning while moving or just moving ?

    Projectile with Drag and g

    I was working on semi-realistic projectile dynamics. The first thing i took was what if a sphere is thrown upwards. g wud act downloads and there wud be drag. Drag=1/2kv^2 (leave k for the moment) (drag depends on v) g=g(R/R+h) (g depends on h) projectile is fired upwards with...
