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
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 ...
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...
