1. (7 MARKS). Determine the minimum torque required to keep the gate closed and vertical under the water head of 3 meters as shown in the figure. Page 2 of 5 Scanned with CamScanner 1. (7 Marks): Two pipes are connected by a manometer as shown in the figure. Determine the pressure difference, pA pB, between the pipes. 3. (8 MARKS). Air flows steadily between two cross sections in a long, straight pipe portion of 10cm inside diameter, where the uniformly distributed temperature and pressure at each cross section are given. If the average air velocity at section (2) is 305m/s. Assume uniform velocity distributions at sections (1) and (2). (a) proof that Vl=67m/s. (b) Determine the frictional force exerted by the pipe wall on the air flow between sections 1 and 2 . 1. (7 MARKS). Determine the minimum torque required to keep the gate closed and vertical under the water head of 3 meters as shown in the figure
