Fluid System & Control Volume & its relationship
• Fluid system refers to specific mass of fluid within
the boundaries defined by a closed surface
• The shape of a system may change with time as a
liquid flows through a constriction
• Control volume refers to fixed region in space which
does not move or change shape
• We choose control volume as a region that a fluid
flows into and out of.
• We call closed boundaries of control volume as
control surface
• Difference between rate of change of “X” within the
system and that within the control volume is equal
to the net rate of outflow from the control volume
