Geology Permeability Kozeny Carman Calculator
Kozeny–Carman intrinsic permeability with independently calibrated grain convention/geometry factor, not hydraulic conductivity. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.
Description
The Kozeny–Carman relation connects grain scale, porosity and an adopted geometric constant to intrinsic permeability.
The Kozeny–Carman relation connects grain scale, porosity and an adopted geometric constant to intrinsic permeability.1
Its result is in area units and depends strongly on the idealized pore structure represented by the model. Use this tool to calculate permeability kozeny carman from the supplied measurements and assumptions.
When to use Geology Permeability Kozeny Carman Calculator
Use this tool to calculate permeability kozeny carman from the supplied measurements and assumptions. Establish the measurement units, sampled interval, calibration or model edition and geological assumptions before entering data.
How to use Geology Permeability Kozeny Carman Calculator and understand its results
- Establish the measurement units, sampled interval, calibration or model edition and geological assumptions before entering data.
- Enter effectiveDiameterM, porosity, calibratedKozenyDenominator, using the field meanings and rules below, then run the tool.
- Read permeabilityM2. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| effectiveDiameterM | Effective diameter m | number | Required |
| porosity | Porosity | number | Required |
| calibratedKozenyDenominator | Calibrated kozeny denominator | number | Required |
Require positive effective grain diameter in meters and positive calibrated denominator constant. Porosity must satisfy 0≤n<1; zero porosity returns zero permeability. Evaluate the specified relation in square meters without choosing a calibration constant.
k_m²=d_m²×n³/[C×(1−n)²] Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| permeabilityM2 | Permeability M2; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
Its result is in area units and depends strongly on the idealized pore structure represented by the model. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
