Thermodynamics And Thermo Science

Thermodynamics And Thermo-Science :

Critical Point of Thermdynamic

                                                                 Thermodynamics is an applied science used in several  branches of 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 from one from 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 wheel .

Thermodynamics principles are used by mechanical engineers the fields of heat transfer , thermofluids and energy conversion . Mechanical engineers use thermo science to design engines and power plants heating ventilation and air condition HAVC systems heat exchangers heat sinks radiators refrigeration insulation and others.        

  

Technical Drawing And CNC:                                                                                 Drafting or technical drawings is the means by which mechanical engineers design products and create instructions  manufacturing parts . A technical drawing can be a computer model or hand-draw  schematic showing all the dimensions necessary to manufacture a part as well as assembly notes a list of required materials , and other pertinent information . Mechanical engineer or skilled worker who create technical two-dimensional process but computer added design  CAD  programs now allow the designer to create in three dimensions.

Technical Drawing

                                                                   Instructions for manufacturing a part must be fed to the necessary machinery either manually through programmed instructions or through the use of the computer added manufacturing  CAM or combined CAD/CAM program. Optionally an engineer may also manually manufacturing a part using the technical drawings. Engineers  manually manufacture parts in the areas of applied spray coatings finishes and other processes that cannot economically or practically be done by a machine.

                                                                                                               Drafting is used in nearly every sub discipline of mechanical engineering , and by many other branches of engineering and architecture . Three dimensional models created using  CAD software are also commonly used in finite element analysis and computational fluid dynamics .
