Fluid Properties Quiz

What is the definition of specific gravity?

• The ratio of mass to volume.

• The volume occupied by a unit mass of fluid.

• The ratio of the weight of a substance to the weight of an equal volume of water.

• The weight of a unit volume of fluid.

Which of the following is a characteristic of ideal fluids?
