A pump supplies water under pressure to a large tank as shown in Fig. P2.89. The circular-plate valve fitted in the short discharge pipe on the tank pivots about its diameter \(A-A\) and is held shut against the water pressure by a latch at \(B\). Show that the force on the latch is independent of the supply pressure, \(p\), and the height of the tank, \(h\).
