Question: The rainwater discharge system in the figure with a width of b=1 m perpendicular to the figure plane is made from point B with the hinged ABC cover. The BC part of the cove. makes an angle of 45 °C with the horizontal. When the reservoir water level reaches 4 m, it is desirable to open the lid and remain open at higher water levels. Neglect the cap weight and determine the required length L of the AB part of the cap by showing the pressure diagrams.
