Water is flowing in a 6 in-diameter pipe line inclined (upward) at a slope of 0.01 ft/ft as shown in Figure P7 .10. If The observed shear stress on the pipe boundary is 0.975 lb/ , (a) what is the slope of The hydraulic grade line (ft/ft)? (b) If the friction factor,/, is calculated to be 0.088, what is the discharge in the pipe? (c) What is the pressure drop across a 1-foot section of this pipe?
