Question 1 of 27070

Most pump manufacturers recommend that the discharge piping for centrifugal pumps be one size larger than the pump discharge nozzle to __________.

🔍 Key Concepts

• Centrifugal pump performance and how discharge pressure is created • Effect of pipe diameter on friction losses in fluid flow • Relationship between pipe size, flow velocity, and friction

💭 Think About

• Think about what happens to fluid velocity in the discharge line if the pipe size is increased compared to the pump nozzle. • Consider how frictional losses change as velocity increases or decreases in a pipe of given length and roughness. • Ask yourself: does a larger discharge pipe usually make it easier or harder for the pump to move fluid at a given flow rate?

✅ Before You Answer

• Review how larger vs. smaller pipe diameters affect friction losses in piping systems. • Recall that the pump develops pressure mainly from impeller design and speed, not from the pipe size alone. • Verify which option directly relates to flow resistance in the discharge line, rather than changing the pump’s inherent pressure capability.
