  • Polytropic process — A polytropic process is a thermodynamic process that obeys the relation::P V^n = C,where P is pressure, V is volume, n is any real number (the polytropic index), and C is a constant. This equation can be used to accurately characterize processes… …   Wikipedia

  • Gas compressor — A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are… …   Wikipedia
