The closed vessel shown contains water with an air pressure of 5 psi (gage) at the water surface. The curved pipe extending from the side of the vessel is closed by a flat, circular flap (with diameter d = 6 in) that is hinged at the top edge as illustrated; the flap is shown from the side. The horizontal axis of the hinge is located h = 2 ft below the water surface. Determine the mini- mum torque that must be applied at the hinge to hold the gate shut. Neglect the weight of the gate and friction at the hinge. Answer: Mhinge 42 ft·lb air 5 psig water T h hinge circular flap 45°

Question
Transcribed Image Text:7. The closed vessel shown contains water with an air pressure of
5 psi (gage) at the water surface. The curved pipe extending
from the side of the vessel is closed by a flat, circular flap (with
diameter d = 6 in) that is hinged at the top edge as illustrated;
the flap is shown from the side. The horizontal axis of the hinge
is located h = 2 ft below the water surface. Determine the mini-
mum torque that must be applied at the hinge to hold the gate
shut. Neglect the weight of the gate and friction at the hinge.
