Which engineering is best chemical or mechanical?

Both branch is good, But compare to Chemical Engineering, Mechanical Engineering has good opportunities. Mechanical Engineering have wider scope and job opportunities in various industries. while Chemical Engineerings have upper edge in the oil refineries sector.

What is heat exchanger in chemical engineering?

Heat exchangers are the basic Heat transfer equipment used in Chemical Process industries for wide range of applications. Varying temperature requirements of streams in a chemical process facilitates the use of heat exchanger.

Is chemical engineering the same as mechanical?

Chemical engineers design and produce the systems, machinery and facilities that use chemical reactions to create products. By contrast, mechanical engineering focuses on the design of systems, equipment and products that rely on motion.

What is design design Machine?

Machine design is an area of study in which one learns to design machine parts by utilizing its whole knowledge and experience in field of mechanical engineering. OBJECTIVES OF DESIGN. DESIGN FOR STRENGTH- safety is first so part to be designed should strong enough to withstand forces in its service.

What is heat exchanger design?

The heat exchanger design is a thermal heat transfer device that exchanges (hence their name) the thermal energy from one source and transfers it to another at different temperatures. In most heat exchanger design, the fluids or gases used to transfer the heat are separated and do not mix.

What are the two types of heat exchangers?

What Are The Different Types Of Heat Exchanger?

• Finned Tube Heat Exchanger Or Air Cooled Heat Exchanger. Suitable for: air/gas to fluid.
• Shell And Tube Heat Exchanger. Suitable for: fluid to fluid / fluid to gas.
• Plate Heat Exchanger Or Gasket Plate Heat Exchanger. Suitable for: fluid to fluid / fluid to vapour.

What is the difference between chemical engineering and Mechanical Engineering?

The American Institute of Chemical Engineers ( AICE) describes chemical engineering as the application of math and science principles to the cost effective develoment of solutions to modern day technical and industrial problems. By contrast, mechanical engineering focuses on the design of systems, equipment and products that rely on motion.

What are the main objectives of heat exchanger design?

The main objective in any heat exchanger design is the estimation of the minimum heat transfer area required for a given heat duty, as it governs the overall cost of the heat exchanger. Many configurations are possible with various design variables such as outer diameter, pitch, and length of the tubes; tube passes; baffle spacing; baffle cut etc.

How to design a shell and tube heat exchanger?

The optimum thermal design of a shell and tube heat exchanger involves the consideration of many interacting design parameters which can be summarized as follows: Process fluid assignments to shell side or tube side Selection of stream temperature specifications. Setting shell side and tube side pressure drop design limits.

What is the application of differential evolution in shell-and-tube heat exchangers?

This report presents the application of Differential Evolution (DE) for the optimal design of shell-and-tube heat exchangers. The main objective in any heat exchanger design is the estimation of the minimum heat transfer area required for a given heat duty, as it governs the overall cost of the heat exchanger.
