System Control Volume
A system is a defined quantity of matter which is considered to analyze the problem. A system is a defined quantity of matter which is considered to analyze the problem.
The system is separated from its surrounding by a boundary which may be real or imaginary and may change shape, volume, and position relative to an observer. The C.V. is separated from its surrounding by a control surface which may be real or imaginary and normally fixed in shape & position relative to an observer. The C.V. is separated from its surrounding by a control surface which may be real or imaginary and normally fixed in shape & position relative to an observer.




Control Volume

  • In a thermodynamic analysis of an open system, such as an air compressor, turbine, etc. attention is focused on a certain volume in space surrounding the system, known as control volume.
  • The control volume bounded by the surface is called “Control Surface”.
  • Both mass and energy can cross the control surface. It may be physical or imaginary.
