[From Bruce Abbott (960104.2015 EST)]
I left something out of equation 7a in my previous post. It should read:
g*m*t/n n
(7a) B = ----------- * --- * (Fr - F0 + Mt)
1 + g*m*t/n m*t
The second ratio in the equation is n/(m*t); I had written it as n/m. Sorry
if this caused any confusion.
Regards,
Bruce
