Energy changes during gas compression
Thread Content
How does the energy of the gas change throughout the entire process in the compressor, from intake to exhaust? Is energy considered from three aspects: kinetic energy, potential energy, and internal energy? How to analyze? We all know that pressure increases. Can pressure really be heightened? And how is this increase in pressure manifested?
Gases are so light that their gravitational potential energy can be ignored; as gas moves from the outside to inside the container, its kinetic energy remains unchanged while its pressure energy increases. As it is blown out, the pressure energy decreases and is converted into kinetic energy
During compression, the machine does work on the air, causing the internal energy of the gas to increase (the rise in temperature is very small, so thermal energy can be ignored). When the gas is expelled, it does work on its surroundings, and the internal energy is converted into kinetic energy; this kinetic energy can then be used in various ways, possibly to provide mechanical energy for other machines.
