Salt water is being discharged into the atmosphere from the two \(30^{\circ}\) outlets at the total rate of \(30 \mathrm{~m}^{3} / \mathrm{min}\). Each of the discharge nozzles has a flow diameter of \(100 \mathrm{~mm}\), and the inside diameter of the pipe at the connecting section \(A\) is \(250 \mathrm{~mm}\). The pressure of the water at section \(A-A\) is \(550 \mathrm{kPa}\). If each of the six bolts at the flange \(A-A\) is tightened to a tension of \(10 \mathrm{kN}\), calculate the average pressure \(p\) on the flange gasket, which has an area of \(24\left(10^{3}\right) \mathrm{mm}^{2}\). The pipe above the flange and the water within it have a mass of \(60 \mathrm{~kg}\).
