Q1 A straight and horizontal pipeline with diameter of 0.8m conveys crude oil (density is 950 kg/mº.
kinematic viscosity is 1.2 x 10-5 m2/s). The pipe wall is assumed to be smooth and the
corresponding friction factor can be found from the Moody Diagram (in the Supplementary
Information sheet). To maintain the oil flow rate, pressure boosters are distributed every 20 km
along the pipeline.
(a) If the oil flow rate is 0.45 m/s, determine the flow state and the amount of pressure that
needs to be raised at each pressure booster.
