Crisco® cooking spray contains canola oil which contains 61% oleic acid (18:1, Δ9), 21% linoleic acid (18:2, Δ9,12) and 9% alpha linoleic acid (18:3, Δ9,12,15), 4% palmitic acid (16:0), and 2% stearic acid (18:0). Please draw the structure for oleic acid, numbering all carbons. Would this be considered an omega 3, 6, or 9 fatty acid? Based on its fatty acid composition, why is canola oil a healthy alternative compared to coconut oil, which contains 91% palmitic acid?

A horizontal pipeline conveying oil (s = 0.8) contains a 60◦bend in which the internal diameter reduces from 200 mm to 100 mm. If the pipe joints on either side of the bend exert no restraint on it, what will be the force an anchorage must resist when the pressure head and the mean velocity of the fluid at entry to the bend are 12 m and 3 m/s respectively? Find also the direction in which the force acts.
