Darcy law calculator - formula & step by step calculation to find the relationship between the fluid viscosity and the presssure drop over a given distance or the total discharge rate through a porous medium. Q = -kA(Pb - Pa)/μL. The porous or soil coefficient of permeability k in m2, cross sectional area to flow A in m2, initial pressure Pb in Pa, final pressure Pa in Pa, fluid viscosity μ in Pa & total length of the pipe or medium in m are the key terms of this calculation.

Formula

In mechanical engineering, the below mathematical formula is used to calculate the relationship between the fluid viscosity and the presssure drop over a given distance.
Darcy law to calculate relationship between the fluid viscosity and the presssure drop over a given distance

In the field of mechanical engineering, sometimes it's important to analyse the relationship between the fluid viscosity and the presssure drop over a given distance for the design & study the pipe lines.
