Test: Fouling Factor - Mechanical Engineering MCQ

Fouling factor for liquid gasoline is 0.0008 while that of clean river, sea water and distilled water are 0.0002, 0.0001 and 0.0001 respectively. Fouling factor = 1/h_S.

There are strong hydrogen bonding between its molecules.

It has low electrical conductivity but this increases with the dissolution of small amount of ionic materials.

Fouling factor for distilled water is 0.0001 while that of Lake River, transformer and lubricating oil are 0.0002, 0.0002 and 0.0002 respectively.

It is a good polar solvent and is referred to as the universal solvent. Fouling factor = 1/h_S.

Fouling factor for engine exhaust is 0.002 while that of industrial liquids, fuel oil and turbine exhaust are 0.0002, 0.0010 and 0.0002 respectively.

It is a neutral, non-polar chemical substance that is viscous liquid at ambient temperature.

Fouling factor for non-oil bearing system is 0.0001 while that of fuel gases, oil bearing system and engine exhaust are 0.0010, 0.0002 and 0.002 respectively.

Fouling factor = 1/h_S.

Fouling factor for liquid gasoline is 0.0008 while that of clean water, sea water and distilled water are 0.0002, 0.0001 and 0.0001 respectively.
