First law applied to a closed system: |
| |
 |
|
Where, |
 |
–
|
Heat added to the system (Path Function) |
 |
– |
Work done by the system (Path Function) |
 |
– |
Total energy change in the system (Point Function) |
First law applied to an open system: |
 |
Where, |
 – Specific enthalpy
 – Velocity of flow
 – Height of inlet and outlet port |
| |
