How does the water that comes out of our sink and shower faucets change temperature when we move the handle(s) back and forth? How does it know to go from hot to cold and visa versa?
In: Engineering
There is a hot and cold water feed that comes into the faucet. The handle moves a valve that changes how much of the hot and cold gets mixed into the stream of water that comes out of the tap.
If the handle is all the way to one side only hot water will come out, if it’s all the way to the other side, only cold water will come out. Somewhere in between it will mix the two together.
