Flow process in thermodynamics

WebThe energy balance for unsteady-flow process, can be simplified using the initial assumptions (v = 0, z = 0, ke = 0, pe = 0) and the mass terms, giving. Q = - m h + m 2 u 2. It should be noted that work and potential energy … WebCh 8 - Thermodynamics of Flow Processes. In this lesson, you will learn to write entropy balance equations for closed systems. Entropy generation is the key because entropy is not conserved ! In this lesson, we develop the entropy balance equation for open systems. We then simplify the equation for SISO, SS, internally reversible processes in ...
