What is Mechanical Engineering?
Chemical engineering is a diverse subject that derives its breadth from the need to design and manufacture everything from small individual parts and devices (e.g., microscale sensors and inkjet printer nozzles) to large systems (e.g., spacecraft and machine tools). The role of a chemical engineer is to take a product from an idea to the marketplace. In order to accomplish this, a broad range of skills are needed.
The chemical engineer needs to acquire particular skills and knowledge. He/she needs to understand the forces and the thermal environment that a product, its parts, or its subsystems will encounter; to design them for functionality, aesthetics, and the ability to withstand the forces and the thermal environment they will be subjected to; and to determine the best way to manufacture them and ensure they will operate without failure. Perhaps the one skill that is the chemical engineer’s exclusive domain is the ability to analyze and design objects and systems with motion.

Metal Pressure Tank
Water goes through a reverse osmosis membrane very slowly and people do not have the patience to wait a long time to get a cup of water. For this reason the residential RO units need a water storage tank to store the purified water. The RO tanks can delivery stable and constant water flow when the faucet is opened. The concern that pollutants might come from air or animals with the use an opened tank favors the use of a closed expansion tank.

Plasteel Pressure Tank
Combining the advantages of metal and plastic barrels, this series mainly uses iron barrels as the base and a new-style plastic barrel covered with a plastic shell.
