Fluid is a substance which offers no resistance to change of
A fluid offers resistance to change in pressure and volume defined by its Bulk Modulus. It also offers resistance to flow provided by a phenomenon called viscosity.
However, there is no resistance to change in the shape of fluids, unlike that in solid.
An ideal flow of any fluid must fulfill the following
Density of water is maximum at
Units of mass density are
Property of a fluid by which its own molecules are attracted is called
Mercury does not wet glass. This is due to property of liquid known as
Property of a fluid by which molecules of different kinds of fluids are attracted to each other is called
The specific weight of water is 1000 kg/m3
The pressure at a point in a fluid will not be same in all the directions when the fluid is
The surface tension of mercury at normal temperature compared to that of water is
For very great pressures, viscosity of most gases and liquids
A fluid in equilibrium can't sustain
According to Archimede's principle, if a body is immersed partially or fully in a fluid then the buoyancy force is _______ the weight of fluid displaced by the body.
A balloon lifting in air follows the following principle
Surface tension has the units of
The stress-strain relation of the newtonian fluid is
The units of viscosity are
When a body is placed over a liquid, it will sink down if
Which of the following meters is not associated with viscosity ?
Dimensions of surface tension are
For manometer, a better liquid combination is one having
The property of fluid by virtue of which it offers resistance to shear is called
The density of water is 1000 kg/m3 at
The ratio of absolute viscosity to mass density is known as
