FM Properties of Fluids

Specific weight of sea water is more than of pure water because it contains

• Dissolved air

• Dissolved salt

• Suspended matter

• All options are correct

Specific volume is reciprocal of :

• mass density

• mass

• volume

• area

…………. Is NOT a property of fluid.

• Mass density

• Area

• Specific volume

• Specific weight

Which of the following is dimensionless ?

• specific weight

• specific volume

• specific speed

• specific gravity

Specific gravity is defined as the ratio of the density of fluid and density of water at which temperature (in °c)?

• 0

• 100

• 4

• It is not dependent on temperature

The specific gravity of water at standard atmospheric conditions is :

• greater than 1

• less than 0

• 1

• 0

The weight density of a fluid to the weight density of a standard fluid is called :

• mass density

• specific weight

• specific gravity

• specific volume

Liquid shapes :

• can be compressed very much

• occupy definite shape

• are not affected by change in pressure and temperature

• none of these

Fluid is a substance which offers no resistance to change of

• Pressure

• Flow

• Shape

• Volume

Assertion (A): In a fluid, the rate of deformation is far more important than the total deformation itself. Reason (R): A fluid continues to deform so long as the external forces are applied

• Both A and R are individually true and R is the correct explanation of A

• Both A and R are individually true but R is not the correct explanation of A

• A is true but R is false.

• A is false but R is true
