vortices... whirlpools, tornadoes, and such.
acceleration = velocity/time
forced vortex:
circulation = tau = 2wA
where w = rotation = average angular velocity (a vector quantity)
A = area enclosed by the contour
free vortex:
circulation = 2(pi)C
then time = 95426120.77903860 seconds (rounded to 16 significant digits)
= 1104.468990498130 days
= 3.025942439720910 years = roughly 3 years + 9.5 days as relative to the rotation and revolution of the planet earth.
a couple other fundamental physical constants to contemplate:
permitivity of free space = 8.854*10^(-12) C^2/(N*m)
permeability of free space = 4(pi)*10^(-7) Wb/(A*m)
SIDD:
the tricky part is .. u cannot maintain a constant acceleration like pi m/s^2 on a massive bodyDoes anyone want details ?
