Notes. An arithmetic mean is obtained from these ratios and denoted by 
. We also have listed the arithmetic mean of the ratio between the velocity field caused by the addition of the toroidal field, and the contraction velocity field. The parameters E, Pr(N0/Ω0)2, and Pm are respectively 10−4, 104, and 102.
