Would you ever believe that a valve with three outlets allow the fluids to flow out of only a single outlet? Yes it is true and such an apparatus is known as three-way stopcock.
A stopcock is a valve used to control the flow of liquid or gases through a tube; it is also used to prevent excess water flow in a domestic water system. Such stopcocks are prepared from glass and rubber. Formation of a three-way stopcock is just similar to an ordinary tap. In a three-way stopcock, the cock is sensitive to direction of flow. It is made in such a way that there is a main tube with a small hole which is attached to another three different tubes arranged perpendicularly to each other. The main tube can be rotated in all the directions, which allows the fluid to pass out through different outlets in required amount.
