Darcy Yeralti Suyu Akimi Analysis - Rezervuar Cikisi Darcy Debisi Calculator

Darcy Yeralti Suyu Akimi Analysis - Rezervuar Cikisi Darcy Debisi Calculator: method and worked example

What the calculation does

Darcy volume flow Q = K A (Δh/L), m³/s. Signed flow indicates direction, not a negative volume.

Example using the prefilled values

Worked example: K=0.0001 m/s, A=50 m², dh=4 m, L=120 m; result = 0.0001666666667 m³/s.

How to interpret the result

Hydraulic conductivity is in m/s; intrinsic permeability in m² is not returned.

Assumptions and limitations

Model assumptions: steady, saturated, single-phase Darcy-regime flow through an approximately homogeneous and isotropic porous medium; consistent SI units and a Newtonian fluid. Hydraulic conductivity K (m/s) depends on the fluid; intrinsic permeability κ (m²) is a different quantity and is NOT calculated here. For hydraulic head differences, a pressure-only conversion to permeability needs density, viscosity and gravitational acceleration. These inputs do not determine pore-scale regime or sample representativeness. Check non-Darcy, unsaturated, anisotropic, compressible and temperature-dependent conditions separately. The effective porosity used in pore-velocity and travel-time estimates may differ from total porosity.
