In the previous article, we discussed Pascal’s law which states the pressure or intensity of pressure at a point in a static fluid is equal in all directions. The Hydrostatic Law states that the increase of pressure in a vertically downward direction must be equal to the specific weight of the fluid at that point. Whereas, […]
Fluid Mechanics is the branch of physics that deals with the behaviour of fluids (liquids, gases, and plasmas) and the forces on them. Fluid mechanics can be divided into two subfields fluid statics, which studies fluids at rest; and fluid dynamics, which studies fluids in motion. Fluid mechanics is based on several mathematical relationships that describe the kinematics, stress, conservation, regulation, and constitutive properties of fluids.
Hydraulic Machines are defined as those machines which convert either hydraulic energy (energy possessed by water) into mechanical energy (which is further converted into electrical energy ) or mechanical energy into hydraulic energy. The hydraulic machines, which convert the hydraulic energy into mechanical energy, are called turbines while the hydraulic machines which convert the mechanical energy into hydraulic energy are called pumps.
What is Pascal’s Law? | Pressure Intensity
In Fluid mechanics, Pascal’s Law states that the pressure or intensity of pressure at a point in a static fluid is equal in all directions. So we need to understand the Fluid pressure at any given point. Let us discuss more details on the Fluid pressure at any given point and the Pascals law. In […]
What is the Gas Constant (R)?
We have discussed the physical properties of Fluids in the previous article. Fluids are either liquids or gases. A Gas constant or Universal molar Gas constant is used to determine the behaviour of a gas under the theoretical conditions. It is denoted by R. Let us discuss more details on the Gas constant. As we […]
What are Surface Tension and Capillarity?
In Fluid Mechanics, Surface tension is one of the important physical properties of fluid among Density and Viscosity. Surface tension is defined as the tensile force acting on the surface of a liquid in contact with a gas or on the surface between two immiscible liquids such that the contact surface behaves like a membrane […]
What is Viscosity of Fluid? | Viscosity Units
In Fluid Mechanics, Viscosity is defined as the property of a fluid that offers resistance to the movement of one layer of fluid over another adjacent layer of the fluid. We have discussed the different physical properties of Fluids in the previous article. In this article, we will discuss the Viscosity of fluid and the […]
Physical Properties of Fluids in Fluid Mechanics
We have discussed the mechanical properties of engineering materials in the previous articles. Fluids (liquids and gases) are also a very important part of engineering. The branch of science deal with the dynamics and mechanics of fluids called Fluid Mechanics. Let us understand a few important terminologies before we understand the properties of the Fluids […]
