You have been hired to consult on a pilot plant project that requires the installation of a rough horizontal pipe made from commercial steel into a flow system. The pipe has a diameter of 4 in. and a length of 30 ft. A Newtonian fluid (heat capacity = 0.149 BTU/Ib_m°F, density = 0.161 Ib_m/ft³, viscosity = 8.88 × 10^-4 Ib_m/ft - sec and kinematic viscosity = 5.52 × 10^-3 ft²/sec) will flow through the pipe at 300 ft³/ min. Assume that the flow is without edge effects, and that the no-slip boundary condition applies. Determine the pressure drop of the fluid as it travels through the pipe.
