Document Summary

Fixed quantity of matter use internal energy (u) E= u + ke+ pe=m (u2 u1)+ 1. Region of space through which mass may flow use enthalpy (h) h+ h+ Creates work from heat transfer (hot -> cold) Uses work to create heat transfer (cold -> hot) Refrigeration cycle, but keeps something hot instead of cold. , where k=thermal conductivity [w /m: k ] =5. 67 10 8 w /m2: k 4 and. Similar efficiency to rankine, cheaper, can use for propulsion or electricity generation. Cv is specific heat at constant specific volume, cp is specific heat at constant pressure. C p= k: r k 1 , c v= r k 1 , Entropy generation rate, for irreversible, steady flow, & adiabatic: k= S @ a given temperature is the entropy generated from 0 k to that temperature: S=s (t 2) s (t 1) r ln( p2.
