Question 1 of 27070

The capacity of a rotary pump, delivering a constant viscosity fluid, will decrease when the discharge pressure is increased, due to __________.

🔍 Key Concepts

• How positive displacement rotary pumps move fluid (trapping and carrying a fixed volume each revolution) • What slippage means in pumps (fluid leaking backward inside the pump from discharge side to suction side) • How increasing discharge pressure affects internal leakage and effective delivered flow

💭 Think About

• If the pump traps essentially the same volume each revolution, why would the actual delivered flow decrease when discharge pressure goes up? • What happens to the tendency of fluid to leak from the high-pressure discharge side back toward the low-pressure suction side as the pressure difference increases? • Which choice directly relates to internal leakage or bypassing inside the pump, rather than conditions outside the pump suction?

✅ Before You Answer

• Identify which answers refer to suction conditions vs. internal leakage (slip) in the pump. • Ask: does increased discharge pressure normally make suction pressure go up or down in a properly supplied system? • Focus on the option that describes more fluid circulating inside the pump instead of going out the discharge, reducing net capacity.
