Understanding renewable energy
by
Renewable energy has increased over the years as they serve multiple advantages over non-renewable energy resources. In fact, renewable energy is known as the cleanest way of generating electricity. They provide a ready supply of power without using natural resources and they have a lower risk of environmental problems like the non-renewable resource. Today you’ll…
Various types of energy and their examples
by
There are different types of energy that can be transformed into other sorts of energy. Energy types are categorized into two basic forms which include Kinetic and Potential. The law of conservation stated that energy can neither be created nor destroyed, but it can be transformed from one type of energy to another. This is…
Forms of energy: kinetic and potential energy
by
Yes, we can say there are several types of energy, but scientifically they are group into two forms such as kinetic energy and potential energy. Today you’ll get to know these forms of energy their formula and examples. It is necessary to understand that while energy can change forms, it is conserved. This means the…
Understanding energy sources
by
All around us, including we humans, energy is one of the common things that occur. Energy is vast, because it takes place in almost every application, starting we ourself, that is the energy we use in surviving, the energy we get from food. There is a different source of energy today that allows human civilization…
Understanding notches and weirs
by
In fluid mechanics, notch and weir is an important topic that cannot be overlooked. These devices are used to regulate the flow of fluid of different sizes and different methods. Notches and weirs are classified based on some considerations which result in different types. Today you’ll get to know the definition, applications, function, components, diagram,…
Understanding buoyancy
by
Have you ever experienced you feeling lighter when swimming in the pool or a bucket feels lighter when drawing water from a well? If you do, buoyancy occurs during those events. In buoyancy, when immersed in water or any source of fluid, a body experiences a force from the downward direction opposite to the direction…
Understanding Archimedes principle
by
Archimedes discovered the buoyancy principle, which is used in various applications including ships. It allows them to float when the weight of the water displaces equals the weight of the ship. Anything shaped to displace its own weight of water before it reaches the point where it will submerge will surely float. Today you’ll get…
Understanding reaction turbine
by
Being a special type of turbine used in hydro-power plants, reaction turbine is used all around the world for the generation of electricity. It is estimated that about 60% of turbines used in hydro-power plants are reaction turbines, though still in competition with impulse turbines. A reaction turbine is constructed of rows of fixed blades…
Things you need to know about gas turbine
by
The gas turbine has been used since 1939 for electricity generation. Today, it is one of the most widely used power-generating technologies. Gas turbines are known to be internal combustion (IC) engines that allow air-fuel mixtures to produce hot gases that spin a turbine to produce power. The process is common in jet engines, automobile…
Everything you need to know about gears
by
Thinking of power transmission today, its common form is through gear. Gears are wheels with teeth and can also be called toothed wheels. A gear is a rotating circular machine part having cut teeth, in the case of a gearwheel, inserted teeth are called cogs, which mesh with another toothed part so that torque can…
Different types of turbine
by
With the vast majority of energy generation and fluid delivery, a turbine is of different types serving the same purpose in various applications. It is a device that harnesses the kinetic energy of some fluid such as water, steam, air, or combustion gases. It turns it into the rotational motion of the device itself. The…
Things you need to know about impulse turbine
by
Impulse turbine is one of the simplest turbines out there, classified as hydro turbines along with reaction turbines. These turbines are group based on how the energy is exchanged between the fluid and the turbine. They are installed to convert the potential energy and kinetic energy of water flow into mechanical work. Hydropower plants extensively…
Difference between impulse turbine and reaction turbine
by
Generally, hydro turbines are classified; impulse turbines and reaction turbines, having some differences between them. A major one is how the energy is exchanged between the fluid and the turbine. Their similarities will be how hydro turbines convert potential energy and kinetic energy of water flow into mechanical. This will be further explained, stick with…
Understanding the different types of fluid flow
by
Previously I explained fluid mechanics where I stated that fluid dynamics is one of its branches, it deals with a fluid flow. This means it involves the motion of a fluid subjected to unbalanced forces. This motion continues as long as the unbalanced forces are exerted. Well, that is not our purpose here. Today…
Understanding fluid mechanics
by
Fluid mechanics is a broad study of fluid behavior (liquids, gases, blood, and plasmas) at rest and in motion. It has a wide range of applications today, this field includes mechanical and chemical engineering, biological systems, and astrophysics. Fluid mechanics study particularly the forces that fluid produces. Today you’ll get to know the definition, applications,…
Things you need to know about Kaplan turbine
by
With the vast majority of turbine out there, Kaplan fall to be one. It works on the principle of axial flow reaction, though some other types work on this principle. In axial flow turbines, water flows through the runner along the direction parallel to the axis of rotation of the runner. Stick with me, this…
Difference between centrifugal and reciprocating pump
by
Centrifugal pumps are known for their simple design and easy operation, while reciprocating pumps are known for their complex shape but highly effective in their operation. The centrifugal pump is also called a rotary pump as it uses the kinetic energy of an impeller to force the fluid and increase the kinetic energy. On the…
Difference between dynamic and positive displacement pump
by
The various types of pumps are categorized into dynamic and positive displacement pumps. A pump which is a mechanical device is used in transporting fluids (liquids or gasses). Its work is achieved by mechanical action converted from electrical energy into hydraulic energy. The dynamic and positive displacement pumps are seen as a device that expends…
Understanding hydraulic pump
by
Just as other pumping devices, the hydraulic pump is another great type used in hydraulic drive systems. It can be hydrostatic or hydrodynamic. Hydraulic pumps are sources of power for most dynamic machines. They have the ability to push large amounts of oil through hydraulic cylinders or hydraulic motors. In this manner, they convert the…
Understanding reciprocating pump
by
A reciprocating pump is a type of positive displacement pump that works on the principle of forwarding and backward movement of a piston. Unlike a centrifugal pump which uses the kinetic energy of the impeller in supplying the fluid. You can quickly read about their difference here This class of positive-displacement pumps includes piston pumps,…
