A machine tool manufacturer is considering using gravity flow to supply cutting oil (SG = 0.87, μ = 0.003 N·s/m2) to the tool and workpiece. The vertical 5-mm diameter tube connecting the oil reservoir to the workpiece is very long so the flow can be assumed fully developed; in addition, the depth of oil in the reservoir is negligible compared to the tube length. The pressure is atmospheric at the exit of the tube and at the surface of the reservoir. Determine the volumetric flow rate of the oil (in cm3/s).
