The 180° return pipe discharges salt water (specific weight 64.4 lb/ft³) into the atmosphere at a constant rate of 1.6 ft³/sec. The static pressure in the water at section A is 10 lb/in.² above atmospheric pressure. The flow area of the pipe at A is 20 in.² and that at each of the two outlets is 3.2 in.² If each of the six flange bolts is tightened with a torque wrench so that it is under a tension of 150 lb, determine the average pressure p on the gasket between the two flanges. The flange area in contact with the gasket is 16 in.² Also determine the bending moment M in the pipe at section A if the left-hand discharge is blocked off and the flow rate is cut in half. Neglect the weight of the pipe and the water within it.
