A double u-tube manometer is connected between the pipelines, as shown in the figure below. Calculate the pressure difference between the water pipe (left) and the oil pipe (right). The water column height in the left tube is 10 inches. Specific gravities of heavy oil (s1), oil (s2), and air (sair) are s1 = 1. 6, s2 = 0. 9, and sair 0, respectively. 2: (21 pt): a 2-m-wide rectangular gate is hinged at the bottom and attached to a buoyant cylinder at the top, as shown in the figure below.
