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…
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,…
Types of wind turbine
by
It is been explained in my previous article that different types of wind turbines use the wind’s kinetic energy to generate power. In fact, wind energy is known as the cleanest way to generate mechanical and/or electrical power. The obtained energy can be classified based on how the wind energy is harvested; land wind and…
Understanding wind turbine
by
In the United States today, a wind turbine is one of the common and most clean ways of generating power. This power generation takes place from a massive wind farm to small turbines powering a single home. Wind turbine around the globe produces clean electricity that is capable of serving a variety of power needs.…
Things you need to know about turbine
by
Thinking of how a working fluid is converted into useful mechanical energy and/or electrical energy, you should think of a turbine. It is known as a turbomachine that contains a moving part called a rotor assembly. The device has vast application which includes automobiles, aerospace, electrical generator, gas turbine engine, etc. Today you’ll get to…
Understanding centrifugal pump
by
In industry today, centrifugal pumps are one of the most commonly used types. It is used to transport fluid by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. This energy typically comes from an engine or electric motor. Today you’ll get to know the definition, functions, applications, components, classifications,…

Ever since the domination of technology, a device “Pump” was invented to raise, transport, or compress fluids. This invention has made life easy in our modern world as it is now used for various purposes. In this article, you’ll get to know the definition, diagram, components, applications, function, classifications, specifications, types, and how a pump…
Things you need to know about pitot tube
by
Thinking of how speed is measured in applications like aircraft is measured, the good pitot tube is the instrument designed for this task. this instrument which is known as a pitot probe consists of a tube with a short right-angled bend. The device is used to calculate velocity depending on the fluid flow. Pitot tubes…
Things you need to know about honing process
by
in MetalworkThe honing process is a micro-finishing process used to obtain perfect hole geometry. Industries today see the great importance of honing machines as the process offers final sizing and creates the desired finish pattern on the interior of tubing or cylinder bores. This process may be considered a machining process because the removal of microchips…
