A pipeline connecting ten tanks contains 10 standard long elbows, 5 globe valves that is half open, and 3 gates valve that is 1/4 open. The line is commercial steel pipe, 40 mm internal diameter, length 200 m. The properties of the fluid are: viscosity 0.99 mNm-2 s, density 998 kg/m3. Calculate the total pressure drop due to friction using equivalent pipe diameters method when the flow rate is 4000 kg/h and f= 0.0032.
