Remarks

・The numerical value in the graph doesn't consider the coverage limitation by Reynolds number.
・Being displayed of "*" means the coverage limitation based on Reynolds number is exceeded.
・Re:Reynolds number of Particle.
・Stokes Region:10^-4<Re<2、Allens Region:2<Re<500、Newton Region:500<Re<100000.
・g=980cm/s^2.
