The entrainment Equation (7) can then be written in the form: 



|T +|S =P(H, -L!^.^!^„K^SK3 (53) 



4) 6 S (p S D 



Moreover, using Equations (10), (49e) , and (49f) 



T = Q.AG cos a + tf , sin a) = 6^j^h-|^^(t,G) (54a) 



S = 6,^(0 sin a - tf, cos a) = 6, h (t,G) (54b) 



The final form of the entrainment equation is
