During the production of biodiesel, glycerin is a waste product and is collected by gravity separation because its sg (1.26) is much higher than that of biodiesel. glycerin is withdrawn from the bottom of the separation tank through a pipe that has p1 = 350 kpa gage, where d = 70 cm and the flowrate is 680 l/s. find the pressure at section 2, which is 0.8 m higher and where the diameter has been reduced to d = 35 cm. assume the flow is inviscid. (gravity acceleration: g = 9.81 m/s2)
