Mechanisms for Energy to Enter/Leave With ingoing/outgoing fluid: Note: Specific (per unit mass) internal energy is used. Heat Transfer (from various sources) Q>0 if heat is added TO the system Work (electrical) s W ± >0 if work is added TO the system. Included in the shaft work term for convenience F

Work of Fluid against pressure (open systems only) As fluid moves, it does work against the fluid that is ahead of it. Work=F dL. But F=PA, and AdL=dV Æ Work=P dV= ˆ P VM Δ THUS WE WRITE But it could be any system Specific MASS volume

Work (Shaft) W ± >0 if work is added TO the system. In the case the system is behaving reversibly, then F=PA, where P is the pressure of the system, which is assumed uniform over A. Then The negative value is added because W ± >0 if dV dt <0 Energy Conservation (First Law of Thermodynamics) Surroundings System Mass in
