its pretty much the same as This

but the coefficient values are different, the problem i'm having is with the coefficients for the bends, could someone please explain what i'm meant to do with them? and where they go in the equation ?

also i'm using the equation H = 4f *(l/d) * (v^2/19.6) is this right ?

cheers for any help guys
