Steady Flow Energy Equation
The energy equation for a control volume is given by Eq. (13.2). At steady state, the first term on the right hand side of the equation becomes zero and it becomes
 | (13.4) |
In consideration of all the energy components including the flow work (or pressure energy) associated with a moving fluid element, one can substitute ’e’ in Eq. (13.4) as
 |
and finally we get
 | (13.5) |
The Eq. (13.5) is known as steady flow energy equation.
