The gate CDE is hinged along CD and can be opened by a normal P acting at point E. It holds a liquid of specific gravity 0.82 above it and is opened to the atmosphere on its lower side. Neglecting the weight of the gate, find (a) the magnitude of force exerted on the gate by direct integration; (b) the location of the center of pressure (the point in which the force acts on the surface); (c) the force P needed to open the gate.
