An oil pump maintains a volume flow rate v through a pipeline of diameter d when the pressure difference is Δp. A mechanic replaced the pipeline with a different one. Both pipelines are of the same length. What pressure difference (Δp new ) is needed to maintain the same volume flow rate v if the diameter of the new pipeline is half that of the old one?
