Extrusion products may be subject to considerable deformation associated with extrusion operations, and some defects can occur in these products. The defects in extruded products can be classified into three categories: Center burst Piping and Surface…

The gas turbine power plant is also called a combustion turbine power plant . The gas turbine is a type of continuous combustion, an internal combustion engine. There are three main components in a gas turbine: An upstream rotating gas compressor; A down…

A comparison of product layout (line) and functional layout (process) in manufacturing  can be made based on workflow, job movement, inventory requirements, machine utilization, capital investment, product quality, work flexibility, space requirements, time required fo…

The fractions formed during the petroleum refining process are fuel gas, propane, butane, light naphtha, heavy naphtha, kerosene, middle distillate, light gas oil, middle distillate, and heavy gas oil. The apparatus boiling temperatures of the fractions are listed bel…

The first gas-cooled reactors with carbon dioxide (CO 2 ) gas as coolant at a pressure of 16 bar and graphite as moderator were developed in Britain. The fuel used is natural uranium, clad with an alloy of magnesium called Magnox. Schematic diagram of a Gas-cooled re…

Gas Metal Arc Welding (GMAW) is also known as metal inert gas (MIG) welding. In this process, the weld area is shielded by an inert atmosphere of argon, helium, carbon dioxide, or other gas mixtures. A wire-feed drive motor automatically feeds the consumable bare wire…

The excellent properties of water as a moderator and coolant make the P ressurized Water Reactor (PWR) a natural choice for power reactors. The most important limitation of a pressurized water reactor (PWR) is the critical temperature of the water, which is 374°C. Thi…
