What statement is true concerning the arrangement and operation of the viscosity sensor as used for sensing the viscosity of heavy fuel oil?

🔍 Key Concepts

• Viscosity and how it affects resistance to flow in a narrow tube (capillary) • Difference between constant speed / fixed capacity and variable capacity pumps • Relationship between pressure drop, flow rate, and viscosity in a capillary tube

💭 Think About

• If the pump runs at constant speed and fixed capacity, what happens to the flow rate through the capillary tube—does it stay constant or change with viscosity? • At a given flow rate through a very small tube, does a thicker (more viscous) oil cause a larger or smaller pressure drop than a thinner oil? • Which pump arrangement (fixed or variable capacity) would make it easier to compare viscosity directly from the measured pressure drop?

✅ Before You Answer

• Identify whether the flow rate in the sensing circuit needs to be constant to relate pressure drop directly to viscosity • Decide whether higher viscosity should give higher or lower pressure drop at the same flow • Match the correct combination of pump type (fixed vs variable capacity) and relationship (proportional vs inversely proportional) that fits basic fluid mechanics in a capillary tube

What statement is true concerning the arrangement and operation of the viscosity sensor as used for sensing the viscosity of heavy fuel oil?

The viscosity sensor is fitted with a constant speed fixed capacity pump and a capillary tube which produces a pressure drop at constant flow which is proportional to the oil viscosity.

The viscosity sensor is fitted with a constant speed fixed capacity pump and a capillary tube which produces a pressure drop at constant flow which is inversely proportional to the oil viscosity.

The viscosity sensor is fitted with a constant speed variable capacity pump and a capillary tube which produces a pressure drop at variable flow which is proportional to the oil viscosity.

The viscosity sensor is fitted with a constant speed variable capacity pump and a capillary tube which produces a pressure drop at variable flow which is inversely proportional to the oil viscosity.
