Properties of Fluid

Ratio of the weight density of a liquid to weight density of standard fluid is

• Equal to the Ratio of the mass density of a liquid to mass density of standard fluid

• more than from the Ratio of the mass density of a liquid to mass density of standard fluid

• Less than from the Ratio of the mass density of a liquid to mass density of standard fluid

• Equal to 1 always

The specific gravity of a liquid has

• the same unit as that of mass density

• the same unit as that of weight density

• the same unit as that of specific volume

• no unit

A beaker is filled with a liquid up to the mark of one litre and weighed. The weight of the liquid is found to be 6.5 N. The specific weight of the liquid will be

• $6.5\frac{kN}{m^3}$

  
  

• 6:5 kN / m

• $1.3\frac{kN}{m^3}$

• None of these

If 200m^3 of fluid has a weight of 1060N measured on the planet having acceleration due to gravity 6.625m/s^2, what will be it’s specific volume?

• 0.8

• 0.7

• 0.6

• 0.5

What is the correct formula for absolute pressure?

• P_abs = P_atm – P_gauge

• P_abs = P_vacuum – P_atm

• P_abs = P_atm+ P_gauge

• P_abs = P_vacuum + P_atm

Bulk modulus is the ratio of

• shear stress to volumetric strain

• volumetric strain to shear stress

• volumetric strain to compressive stress

• compressive stress to volumetric strain

Shear stress in static fluid is

• always zero

• always maximum

• between zero to maximum

• unpredictable
