Velocity of liquid hydrocarbon fuels in a pipeline can not be measured by magnetic flowmeters, because their __________ is very low/small.

A. Thermal conductivity

B. Electrical conductivity

C. Specific gravity

D. Electrical resistivity

Answer: Option B

Solution(By Examveda Team)

In this question, the inability to measure the velocity of liquid hydrocarbon fuels in a pipeline using magnetic flowmeters is due to their electrical conductivity being very low or small. Magnetic flowmeters operate based on Faraday's law of electromagnetic induction, which requires the fluid to be electrically conductive to generate a measurable signal. Since liquid hydrocarbon fuels typically have low electrical conductivity, magnetic flowmeters are not suitable for measuring their velocity.

Hence, Option B: Electrical conductivity is the correct choice.
