Bruhn erratum
Bruhn erratum
(OP)
humbly i propose this thread ...
bruhn was human and his book has errors. that is not meant as a slight against one of our "bibles". McCombs has prepared an equally valuable supplement.
almost all of us use bruhn everyday and i thought it'd be helpful to everyone to post an erratum.

"V^2 - Vo^2 = 2as"
(first velocity term must be squared)
And then there's the previously mentioned page B1.8, Equation 3,
"...= f/F0.7 + (3/7)*(f/F0.7)n

Equation (69) should have a "tan α" term at the end. The full equation should read:
M=(1/12) k fs t d2 C3 tan α
