What is meant by compressibility of a liquid?
Compressibility is the property of being reduced to a smaller space by pressure. The compressibility of fluid is basically a measure of the change in density that will be produced in the fluid by a specified change in pressure.
What is a simple definition of viscosity?
viscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow. Molasses, for example, has a greater viscosity than water.
What is the difference between viscosity and pressure?
Viscosity is normally independent of pressure, but liquids under extreme pressure often experience an increase in viscosity. Since liquids are normally incompressible, an increase in pressure doesn’t really bring the molecules significantly closer together.
What is isentropic compressibility?
Since definition of compressibility involves change in volume due to change in pressure, hence compressibility can be isothermal, where volume change takes place at constant temperature or isentropic where volume change takes place at constant entropy.
What is compressibility example?
1)LPG gas : We fill these cylinders with the fuel gas in a high pressure, that’s why the gas is stored as a liquid inside the cylinder. 2)Coke:We fill coke bottles with high pressure carbon dioxide,to make the fizz in the soft drink.
What is the difference between compressibility and consolidation?
The compressibility of soil is defined as the capability of soil to decrease its volume under mechanical loads, whereas the consolidation is the compression of saturated soil under steady pressure and it is occurred as a result of water expulsion from the soil voids.
What is the another name of viscosity?

What is the difference between viscosity and coefficient of viscosity?
Viscosity is a resistance induce between two adjacent layer of liquid while it flows. While coefficient of viscosity is tendency of that resistance.
What is unit of compressibility?
Usually, when we are talking about compressibility we can say that it is the inverse or reciprocal of the bulk modulus of elasticity. The SI unit of compressibility is mostly given as m2/n.
What is the difference between specific gravity and viscosity?
Specific gravity is defined as the ratio of the weight density of a fluid to the weight density of a standard fluid. Viscosity is defined as the property of a fluid which offers resistance to the movement of one layer of fluid over adjacent layer of the fluid.
What is the compressibility of fluid?
The compressibility of fluid is basically a measure of the change in density that will be produced in the fluid by a specified change in pressure. Gases are, in general, highly compressible whereas most liquids have very low compressibility. The fact that compressibility effects can have a large influence on fluid flow.
What is the difference between compressibility and compresscavitation?
Cavitation results in the formation of vapour pockets or cavities which are carried away from the point of origin and collapse at the high pressure zone. Compressibility is the reciprocal of the bulk modulus of elasticity, K which is defined as the ratio of compressive stress to volumetric strain.
