🔍 Key Concepts

• Positive displacement blowers and how they move a fixed pocket of air each revolution • Relationship between rotational speed (rpm) and the number of air pockets moved per unit time • Whether a Roots blower output depends more on how fast it turns or on engine power/fuel usage

💭 Think About

• Ask yourself: in a Roots-type blower, does each revolution move a fixed amount of air, or does that amount change with load or fuel burn? • Which of the choices changes in direct step with how many revolutions per minute the blower is turning? • Is brake specific fuel consumption a flow, a ratio, or a speed-related quantity?

✅ Before You Answer

• Verify which option is most directly tied to rotational speed (rpm) of the blower • Identify which quantities (load, brake horsepower, BSFC) can change without a strictly fixed relationship to blower rpm • Confirm that a positive displacement device delivers nearly the same volume per revolution, so total volume per minute depends on how many revolutions occur per minute
