Energy Transfer by Heat, Work, and Mass
Learning Objectives
I.Identify the types of energy that may be transferred to or from a thermodynamic system. |
 |  |  | II.Define the meaning of heat transfer and work. |
 |  |  | III.Determine that energy in the form of heat or work may cross the boundaries of a closed (fixed mass) system. |
 |  |  | IV.Examine the various forms of work, with particular emphasis on the moving boundary work or PdV work commonly encountered in reciprocating devices such as automotive engines and compressors. |
 |  |  | V.Determine that a fluid flowing across a control surface of a control volume carries energy across the control surface in addition to any energy transfer across the control surface that may be in the form of heat and/or work. |
 |  |  | VI.Identify the energy carried by a fluid stream crossing a control surface as the sum of internal energy, flow work, kinetic energy and potential energy of the fluid and to relate the combination of the internal energy and the flow work to the property enthalpy. |
 |  |  | VII.Discuss the conservation of mass principle. |
 |  |  | VIII.Apply the conservation of mass principle to various systems including steady- and unsteady-flow control volumes. |
