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.
