Part of the mechanism of a toilet is the system that refills the toilet tank after a flush. A conceptual sketch is shown below. Water enters the tank through an annular opening around the plug; eventually the water level, WL, in the tank rises and the float also rises, pushing down the plug and turning off the supply of fresh water. Draw a block diagram of the system, indicating on the diagram which parts of the conceptual sketch correspond to the blocks.
