A pipeline connecting three 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 velocity heads method when the flow rate is 4000 kg/h and f = 0.0032. a. 70850 KN/m2 T b. 60532.21 KN/m2 C. 80234.34 kN/m2 d. 1245782 KN/m2
