Question

devise a control system to fill a container with water after it is emptied through a stopcock at the bottom. the system must automatically shut off the water when the container is filled.

Answer 1

It is a simple schematic representation that illustrates the principle of an ordinary filling system in toilet tank.

The ball in the toilet tank floats in water. As the ball gets over to the top of the container, the stopper present in it decreases the flow if water.

When the container is filled, the stopper shuts automatically.
