Description
Rescale pressure loss to a reference density.
Physical process calculations combine supplied geometry, material properties and pressure or gas-state conventions. A density scaling, ideal-gas correction or vessel-volume term can be dimensionally consistent without verifying the actual fluid state, flow regime or equipment suitability.
Rescale pressure loss to a reference density.
When to use this tool
Use Pressure Loss Reference Density Factor when evaluating the stated geometric, fluid-property or gas-state term.
How to use the tool and how it works
- Enter pressureLoss, measuredDensity, referenceDensity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read referencePressureLoss. Use the output convention below.
Rescale pressure loss to a reference density. Require pressureLoss >= 0 and positive measured/reference densities; referencePressureLoss = loss*referenceDensity/measuredDensity.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| pressureLoss | Pressure Loss | Required. Finite number; minimum 0. |
| measuredDensity | Measured Density | Required. Finite number; strictly above 0. |
| referenceDensity | Reference Density | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| referencePressureLoss | Reference Pressure Loss | Required. Finite number. |

}Limitations and assumptions
- This assumes a compatible fixed-velocity loss scaling; flow regime, friction, compressibility and actual pressure drop are not predicted.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified geometry and state-specific material data with an appropriate full engineering model for actual flow, storage or equipment design.
