Derivation of the 141.2 constant
141.2 is the well know constant with is used for converting from the Darcy's law units to the field units
Math and Physics
Darcy's law:
In Darcy's units:
![\frac{[cm^3]}{[sec]} = \frac{[D][cm^2]}{[cP]} \frac{[atm]}{[cm]}](/images/math/a/f/9/af984ae2e14ce0e0cb11acd81114eedb.png)
Converting to the filed units:
![\frac{[cm^3] \frac{[ft^3]}{[30.48^3 cm^3]} \frac{[bbl]}{[5.61458333 ft^3]} }{[sec] \frac{[day]}{[86400 sec]}} = \frac{[D][cm^2]}{[cP]} \frac{[atm]}{[cm]}](/images/math/f/3/e/f3eef86fbda518a3e2ec104a2657ecfe.png)
