Q

The capacity of a gear type rotary pump, when operated at a constant speed, will decrease with an increase in the pump __________.

🔍 Key Concepts

• Positive displacement pumps like gear-type rotary pumps move a fixed volume per revolution • How internal leakage or slip inside the pump affects its actual delivered capacity • The effect of clearances, pressure conditions, and mechanical ratings on flow rate at a constant speed

💭 Think About

• Think about which factor would cause more fluid to recirculate inside the pump instead of being discharged, even though the pump speed stays the same • Ask yourself: which option changes the actual delivered flow at the outlet, and which options are more about conditions or limits rather than flow loss? • Consider what happens inside the pump if parts wear over time—how would that change capacity?

✅ Before You Answer

• Identify which option directly increases internal leakage (slip) in a gear pump • Distinguish between a pump’s design ratings (like torque) and its actual volumetric output • Verify which variable, when increased, would make the pump less efficient at moving fluid forward at the same RPM
