Mechanical engineering including mechanical and chemical engineering. At its simplest, thermodynamics is the study of energy, its use and transformation through a system. Typically, engineering thermodynamics is concerned with changing energy from one form to another. As an example, automotive engines convert chemical energy (enthalpy) from the fuel into heat, and then into mechanical work that eventually turns the wheels. Thermodynamics principles are used by mechanical engineers in the fields of heat transfer, thermofluids, and energy conversion. Mechanical engineers use thermo-science to design engines and power plants, heating, ventilation, and air-conditioning (HVAC) systems, heat exchangers, heat sinks, radiators, refrigeration, insulation, and others.
Port of Dalian million tons in 1995. In 2016, cargo throughput for the Port of Dalian reached 355 million tons, which was up 5.5% from 2015. Lifting capabilities are between 3 – 120 tons at working radius 3 – 30 meters. The Port of Dalian's DCT, DPCM, and DICT have a total of 13 berths with alongside depths from 9.8 to 16 meters (32.2 to 52.5 feet) The port is around 503.55 mi (932.58 km, from Koje (South Korea) To Dalian (China).
