| U =
mu, u(internal energy per unit mass), |

| KE =
(1/2)mV2 and PE = mgz |

| Flow
work Wflow= m (p/r) |
||||
| It is
common practice to combine the total energy with flow work or flow work. |
||||
| Thus: |

|
|
| The
difference between energy in and out is due to heat transfer (into or out) |
|
| and work done
(by or on) the system. |
