Question
A hydrocarbon oil (Viscosity 0.025 Pa.s and density 900 kg/ m³) is transported using a 0.6 m
diameter, 10 km long. The maximum allowable pressure drop across the pipe length is 1 Mpa. Due
to a maintenance schedule on this pipe line. It is required to use a 0.4 m diameter 10 km long pipe
to pump the oil at the same volumetric flow rate as in the previous case. Estimate the pressure drop
for the 0.4 m diameter pipe. Assume both pipe to be hydraulically smooth and in the range of
operating conditions. The Fanning friction factor is given byf 0.079 Re
