| Parameter | Description |
|---|---|
| Flow | Cumulative flow for the system, based on the flow for individual components in the system. |
| Reynolds Number |
 Calculation formula |
| Relative Roughness |
 |
| Flow State | The Flow State is determined by the value of the Reynolds Number. A Reynolds Number less than 2,000 is considered laminar flow. A Reynolds Number greater than 4000 is considered turbulent flow. Numbers between 2,000 and 4,000 are unpredictable and no loss calculation is made. Two types of turbulent flow: transition and complete turbulence. |
| Friction Factor | Friction factor used in Darcys equation is calculated based on the flow state  Laminar Flow  Turbulent Flow |
| Velocity |
 |
| Friction | The pressure loss for a specific length unit of pipe. |
| Pressure Drop | The total pressure drop for the entire length of pipe. |
