MlinConlnnt P 14 O I 5 Points In old buildings, when closing a tap, you might hear a series of loud bangs. This is known as a water hammer and is caused by the sudden closing of a valve which immediately stops flowing water. Since the flowing water is moving at a certain speed it must be decelerated to stop, this implies a force being applied on the water near the valve to stop it. However, this force can often be transmitted very far along the pipes causing them to move slightly and create a banging sound. a} Why is the force applied to the water near the valve transmitted a significant distance along the pipes? (1 point) bl How could you alter the system to remove the hanging sound? [2 points) :2] If instead of a liquidI you were closing a tap for a gas, would this happen? Explain.
