Query on equation for W(1.35Reh)
Hello Dear reader of this email, I am trying to check the equation for calculating f for open channel flow. The top line of the last term of the equation of W(1.35Reh) is given as (ln([ln1.35Reh]^2) - 2*ln(ln1.35Reh)). As I unerstand logs, the two terms on the top line are equal, thus, the last term for W(1.35Reh) will always be zero. Could you, or some other very helpful person, check the equation for W(1.35Reh) to confirm there might be an error in the last term, please? Regards.
