🔍 Key Concepts

• pump affinity laws for centrifugal pumps • relationship between impeller diameter and flow (discharge) at constant speed • how changes in size affect flow, head, and power differently

💭 Think About

• Think about which variable (flow, head, or power) changes most strongly when you increase impeller diameter slightly at the same speed. • Ask yourself: if you double the impeller diameter and keep speed the same, does flow simply double, or does it change by a power (square or cube) of that change? • Consider that different performance characteristics (flow vs head vs power) each follow a different mathematical relationship to impeller diameter.

✅ Before You Answer

• Identify which of the choices matches the affinity law for how flow (Q) changes with impeller diameter at constant RPM. • Make sure you are focusing on flow/discharge, not head or power, since each has a different exponent in the pump laws. • Check whether any option incorrectly mixes in efficiency instead of the basic geometric/kinematic relationship.
