Jet Engine vs Rocket Engine The jet and rocket engines are reaction engines based on Newton’s third law. Rocket engine is also a jet engine with few specific variations between the two. The thrust of the two is from the speed of the exhaust of the engine. The exhaust of a rocket engine reaches the […]
Difference Between Steam Engine and Steam Turbine
Steam Engine vs Steam Turbine While, steam engine and steam turbine use the large latent heat of vaporization of steam for the power, the main difference is the maximum revolution per minute of the power cycles that both could provide. There is a limit for the number of cycles per minute that could provide with […]
Difference Between Two and Four Strokes
Two vs Four Strokes The internal combustion (IC) engines are classified as two and four strokes engines. The difference between the two is the number of times the piston moves up and down in the cylinder to complete one combustion cycle, named as Otto Cycle (Suck, Squeeze, Bang and Blow of the air and fuel […]
Difference Between Mechanical Seal and Gland Packing
Mechanical Seal vs Gland Packing Mechanical seals and gland packing are integral parts of all pumps and shafts and used in many engineering applications. Both types of seals are used commonly and it depends upon budget, requirements and personal choice. However, there are differences in features of the two types of packing and one must […]
Difference Between Roller Bearing and Ball Bearing
Roller Bearing vs Ball Bearing A bearing is a device that is used in between two moving or rotating surfaces to facilitate smooth movement and to reduce friction. Bearings have a long history and even before the modern types of bearings came into existence, man used different objects that helped in transportation of large, heavy […]
Difference Between Braze and Weld
Braze vs Weld Braze and weld are two kinds of process to join two different parts, usually metals, to get the desired length or shape. These two processes are also used to fix a broken length of metal or fill some gaps in between metal joints to make these stronger. Braze A braze is a […]
Difference Between Hose and Pipe
The key difference between hose and pipe is that hoses are more flexible and are made of materials like rubber and plastic, while pipes are more rigid and are made of materials like metal and PVC. Hose and pipe are lengthy hollow cylinders we use to transport liquids. They are efficient in transferring liquids from one […]
Difference Between Centrifugal and Reciprocating Pump
Centrifugal vs Reciprocating Pump Pumps are devices used for displacement of fluids from one place to another. There are many types of pumps out of which more popular ones are centrifugal and reciprocating pumps. Though they serve the same purpose of transportation of liquid, there are many differences in their features and working principle that […]
