70% to passThe viscosity of a residual fuel oil is measured in Saybolt _______________.
ASeconds Furol
BMinutes Universal
CMilliliters Universal
DMillimeters Universal
AI Explanation
The correct answer is A) Seconds Furol. The viscosity of a residual fuel oil is measured in Saybolt Seconds Furol, which is a standard unit of measurement for the viscosity of fuel oils. The Saybolt Seconds Furol test measures the time it takes for a specific volume of the fuel oil to flow through a standardized orifice, and this value is used to determine the viscosity of the oil. The other answer choices are incorrect because they do not accurately represent the standard unit of measurement for residual fuel oil viscosity. Options B, C, and D refer to units of measurement that are not typically used for this purpose.
