resistances on the hull of the ship

The design of the hull of ships and boats is quite a challenging job because there are quite a number of variables that should be taken into account. One of the calculations that is quite important in hull design is resistance, because the…

material fatigue

Fatigue is a material damage caused by repeated loading for a long time. If a metal is subjected to repeated loads (stress or strain), the metal will fracture. Damage due to repeated loads is called fatigue failures, generally this occurs after…

main processes of oil and gas production

The oil and gas industry is one of the industries that demands highly engineered and varied processes. In this article, we will discuss some of the most common processes encountered in the oil and gas production process. An Examples of the…

chemical reactors

Chemical reactors are undoubtedly the most important part of the chemical, biochemical, polymer and petroleum process manufacturing processes. A chemical reactor is a container that converts raw materials into chemicals that we will make as…

centrifugal compressor

The compressor has the function of compressing/compressing the gas fluid into a small volume so that the temperature and pressure of the gas fluid increases. In other words, the compressor receives a mass flow of gas with a low temperature…

wind turbine blade design

The use of wind as an energy source has been used for hundreds of years to pump water or grind corn, this equipment is also known as a windmill. In the 19th century, fossil fuels replaced the use of these large, heavy, inefficient windmills.…

airplane wing design

In principle, an airplane can fly because its wings generate lift force. The principle of the formation of lift can occur because of the "suction" of air upward due to the shape of the airfoil that is designed in such a way. The formation of…

extended surface heat exchanger
