Control volume refers to

Control volume refers to Correct Answer A fixed region in space

Explanation:

A control volume is a fixed, identifiable region in space through which fluid flows. The boundary of the control volume is called a control surface.

Types of System

Control Mass System (Closed System)

  • It is a system of fixed mass with a fixed identity
  • This type of system is usually referred to as "closed system"
  • There is no mass transfer across the system boundary
  • Energy transfer may take place into or out of the system

Control Volume System (Open System)

  • It is a system of fixed volume
  • This type of system is usually referred to as "open system” or a "control volume"
  • Mass transfer can take place across a control volume
  • Energy transfer may also occur into or out of the system
  • A control volume can be seen as a fixed region across which mass and energy transfers are studied
  • Control Surface- It is the boundary of a control volume across which the transfer of both mass and energy takes place
  • The mass of a control volume (open system) may or may not be fixed
Most of the engineering devices, in general, represent an open system or control volume.
