Fluid Mechanics (Physical Properties of Fluids)
Indicate whether the statements are correct
or incorrect.
1. Density is the ratio of mass of unit
volume of liquid to the mass of unit volume of water.
2. In the gas equation temperature should
be used in Kelvin scale.
3. Specific weight is the mass of unit
volume.
4. The cohesive forces are highest in gases.
5. The shear force in solid is proportional
to the deformation.
6. In fluids the shear force is
proportional to the rate of deformation.
7. Newtonian fluid is one whose viscosity
will increase directly with rate of deformation.
8. The vapour pressure will vary with
temperature.
9. Ideal fluid has zero viscosity and is
incompressible.
10. Gases can be treated as incompressible
when small changes in pressure and temperature are involved.
