Q1: (a) Rapid fluctuation of water pressure in a fire hose. Q2: (a) Sudden changes in water flow velocity. Q3: (d) All of the above. Q4: (d) All of the above. Q5: (b) The length of the hose line. Q6: (c) Open and close the fire hydrant slowly. Q7: (a) Hydrant valve damage. Q8: (d) All of above. Q9: (d) All of the above. Q10: (d) All of the above.

More Information

Water hammer, or hydraulic shock, occurs when there's a sudden change in water flow, leading to pressure surges that can damage equipment and hydrate valves.

Tips

A common mistake is not recognizing air in the system or sudden valve closures as contributing factors to water hammering.
