what is Reynolds number in my case, help please
 
Re=density*velocity*dia/ viscocity fluid is air , dia=1m , velocity is 40m/s


Viscosity for air got 1.7894e-5 kg/ms density= 1.225 Kg/m3



I want to simulate air at 40m/s flow past a 2D cylinder.

Re.No= 1.225*40*1/(1.789*10^-5)= 2.738*10^6
this is so simple....what's the issue?
