In an air-cooling system, the outer surface of the cylinder and cylindrical head in reciprocating engine is cooled by air flowing over them. To increase the heat transfer rate from the surface, the metallic fins are cast on the cylinder and cylinder head. These fins in…

Losses in steam turbines can be mainly classified into two types. They are: Internal losses (which occur within the flow of Steam) and External losses (which occur outside the turbine casting. Internal Losses in Steam Turbines: The internal losses in ste…

When the surfaces of bearing are separated by a fluid film, the bearing materials do not have any effect on its operation so long as the parts have sufficient strength to withstand the imposed loads and sufficient rigidity to maintain alignment. On account of streng…

The manufacturing industry is pacing at breakneck speed, and innovations, too are so focused that every segment of manufacturing right from designs to finishing processes have uplifted pointedly. Industry pioneers project two major factors that are driving these innova…

Disc brakes were mostly used in motocross, however, they have recently been used in off-road bikes as well, such as mountain bikes. Since the disc provides a powerful brake, they are ideal for all weather and terrain, as well as for trail riding. Rather than using so…

When deciding on which heat-transfer fluid best suits your needs, there are some crucial factors to take into account. In solar water heating systems, these fluids are responsible for transporting heat through heat exchangers and solar collectors to the heat storage ta…

A plate and frame heat exchanger (PHE) is often a preferred option because of excellent heat transfer capability. When using this type of unit, there are several critical factors that should be considered. For example, if the plate and frame heat exchanger will be used…
