• TRUE

• FALSE

• Maybe

• I don't know

A property of fluid that is defined as the ratio of mass of the fluid to its volume.

• Mass Density

• Unit Weight

• Specific Gravity

• Specific Weight

A property of a fluid that is defined as the ratio between the weight of a fluid to its volume.

• Density

• Unit Weight

• Specific Gravity

• Mass Density

This property of fluid is the reciprocal of mass density.

• Weight Density

• Specific Volume

• Unit Weight

• Specific Gravity

This is defined as the ratio of the density of a substance to the density of some standard substance at a specified temperature. It can be also defined as the ratio of the weight density of a fluid to the weight density of a standard fluid.

• Relative Density

• Specific Volume

• Weight Density

• Mass Density

Answer explanation

Relative Density is the other term for Specific Gravity
