Engine: Motor Plants and Auxiliary Boilers

1. A For a constant operating temperature, the greater the specific gravity of the oil the larger the regulating ring.
2. B The specific gravity of the oil and the size of the regulating ring are related only during the initial design stages of the centrifuge.
3. C With oils of greater specific viscosities it is proper to select smaller regulating rings regardless of the operating temperatures desired.
4. D The larger sized regulating rings are designed to be used with oils of lower specific gravities.
