From Equations 7-39 and 7-40, 



7r35 1

(12.2)(4) 



^^ -^ - 4.88 X 10\ 



1 X 10-5 



Co = 0.7 , 

 and from Equation 7-46, with Rg > 5 x 10^ , 



(35) (0.405) = 17,200 lbs., 



Fom = Co ^ Pg D H^ K^^ , 



^Dm ^ (0.7) (0.5) (2) (32.2) (4) (35)2 (037) ^ 40,800 lbs., 



H-m = Ffm 'I S.^ =" (17,200) (85) (0.62) = 906,000 ft. lbs., 



^Dm = ^Bm ^ ^Dm = (40,800) (85) (0.82) = 2,840,000 ft. lbs. 

 From Equation 7-34, 



^M^ 1.5 (4) 



W = = -^ = 0.245 . 



C^H 0.7 (35) 



Interpolating between Figures 7-49 and 7-50 with H/gT^ = 0.00755 and 

 d/gT^ = 0.0183, 



<Pm = 0.20 . 

 Therefore, from Equation 7-35, 



F»x = <^m w Co H^D, 



F^ = (0.20) (64) (0.7) (35)2 (4) ^ 43,900 lbs.
