A circular gate of 0.6m
radius is hinged so it rotates about the horizontal diameter i.e. it rotates
about a horizontal line passing through the centroid of the gate. The gate is
at the end of a pipe discharging to a river. Measured above the centroid of the
gate the head in the pipe is 7m while the head in the river is 3m. Assuming
the gate is initially verticala)Calculate the force
exerted by the water in the pipe on the gate and the distance GP between the
centre of the gate G and the centre of P;b)Calculate the force
exerted by the river water on the gate and the distance GPc)By taking moments about
the hinge using the results from above determine the net turning moment on the
gate caused by the two forces acting at their respective centres of pressure on
opposite sides of the gate.
