In the case of turbulent flows, first, application of the integral form of the energy equation yields an expression for the major head loss (Equation 6.51). Derive the expression for the unknown pressure drop, Δp, explain why one cannot analytically determine the pressure drop, Δp (or the unknown friction slope, Sf in the case of turbulent open channel flow), and state how it is actually determined.
