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

Question

Accepted Answer

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.

Answer

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.

Answer

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.

Answer

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.
