🔍 Key Concepts

• Water hammer as a pressure surge in pipes • Effect of sudden changes in flow velocity in a piping system • Role of valve operation vs. pump starts in causing pressure shocks

💭 Think About

• Which choice involves the most sudden change in water velocity inside the pipe? • Which condition would create a sharp pressure spike rather than a slow change in pressure level? • Think about when you’ve heard pipes bang or rattle at home—what kind of action caused it?

✅ Before You Answer

• Identify which option involves rapid stopping of moving water rather than a gradual change. • Ask: does this condition create a shock wave in the pipe or just a lower/steady pressure? • Eliminate any choices that only affect tank level or volume without a sudden change in flow.
