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