meter per day
Speedexact by definition
The metre per day is exactly 1/86,400 of a metre per second. It is the standard unit for hydraulic conductivity and groundwater seepage velocity in metric hydrogeology, where flows of a few metres a day are typical of sand aquifers. The factor is exact by definition.
Watch out: Darcy velocity and actual pore velocity are different numbers in the same units. The Darcy flux divided by the effective porosity gives the real speed a contaminant travels, which is typically three to five times larger.
