IrrigationQuestion 8 of 100
Water hammer in an irrigation system is BEST reduced by which measure?
a.Increasing water velocity above 10 feet per second
b.Removing all valves
c.Using undersized pipe
d.Keeping velocity below about 5 feet per second and using slow-closing valves
Explanation
Water hammer is a pressure surge caused by fast-moving water stopping abruptly, often from quick-closing valves. Keeping design velocity at or below about 5 feet per second and using slow-closing solenoid valves reduces the surge. Oversized surges can burst pipe and fittings over time.
