Difference Between

2 Pole vs 4 Pole Motors   A motor is an electric device that converts electrical energy into mechanical energy, specifically in the form of torque delivered through a shaft. The motors operate on the principle of electromagnetic induction as described by Michael Faraday. 2-Pole Motor A motor that contain... 

Exhaust vs Muffler   Any internal combustion engine produces exhaust gasses through the combustion process. The byproducts of the combustion are toxic and harmful to the environment and obviously to the passengers too. Therefore, exhaust has to be released with a controlled output to minimize the harmful... 

Rocket vs Missile   When discussing about rockets the impression is that they are high tech and complicated machinery used in defence and space exploration. Even these are often related to almost fantastical feats in human history; rockets have both simple and ancient origins. Today they are used in many... 

Kaplan vs Francis Turbine   Water, always in motion, carries energy with it. Humans have always wondered at the tremendous power of it and often made use of the power. But, only in the wake of the 19th century, engineers developed machinery to harness this energy with efficiency. Turbines are the machines designed... 

Drilling vs Boring   Drilling and boring are two methods of machining used in manufacturing. Both methods are used for creating or enlarging a circular hole in the material. More about Drilling Drilling is the cutting process of a material using a specially designed rotating cutting tool called a drill bit.... 

Impulse Turbine vs Reaction Turbine   Turbines are a class of turbo machinery used to convert the energy in a flowing fluid into mechanical energy by the use of rotor mechanisms. Turbines, in general, convert either thermal or kinetic energy of the fluid into work. Gas turbines and steam turbines are thermal turbo... 

Chain Drive vs Belt Drive   Chain drive and belt drive are two mechanisms used in power transmission. The power output from an engine in the form of torque delivered by the crankshaft or axle is transferred to another rotating body such as an axle or a wheel using closed loop of chain or belt. It is one of... 

Pump vs Turbine   Pump and turbine are two devices that are widely used in many industries. The turbine is a device that is capable of gathering energy and converting it to work. The pump is a device that is used to move fluids. Both of these devices are very important in fields such as electrical engineering,... 

Pump vs Motor   Pump and motor are two devices that are widely used in many industries. The motor is a device that is capable of rotating when a voltage is applied. The pump is a device that is used to move fluids. Both of these devices are very important in fields such as electrical engineering, mechanical engineering,... 

Safety Valve vs Relief Valve   Whenever a gas or a liquid is used as the working fluid of a machine, whether it is large or small, it is transported under pressure. Sometimes the pressure in these systems and interconnecting piping can be so large that a breakage can result in catastrophic damages, even loss... 

Carburetor vs Fuel Injection   In an internal combustion engine, the fuel- air ratio of the fuel air mixture has significant influence on the performance of the engine, since it directly controls the power output of the engine. Carburettors and Electronic fuel injection systems are devices used to mix fuel... 

MIG vs TIG Welding   MIG and TIG welding are two types of arc welding, using metal electrodes and an inert gas as the shielding from oxidation at high temperatures.  Both types of welding are relatively easy to learn, and the welding processes can be performed on all the common materials. What is MIG welding? MIG... 

Supercharger vs Turbocharger   One of the key factors affecting the efficiency of any internal combustion engine is the air supply. If the air supply is lower than the required, the fuel-air mixture undergoes partial combustion inside the combustion chamber/cylinder and the net power delivered is lower than... 

Internal vs External Combustion Engine   Internal combustion engine and external combustion engines are types of heat engines using thermal energy produced by combustion as the main source of energy. In simple, both these machine types convert thermal energy into mechanical work in the form of rotation of... 

Piston vs Plunger   Piston pumps and plunger pumps are two types of positive displacement pumps working based on a reciprocating mechanism. They are the most commonly used type of reciprocating pumps to transport gasses or liquids at a very low to 150 MPa pressure. What is a Piston Pump? Operation of the piston... 

Compressor vs Blower   Compressors and blowers are machines used to transport gasses, and change their fluid properties, especially the properties related to pressure. In many industrial applications, these devices can be found because air or some other gas is used as the working fluid, and it needs to be...
