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 filed units:
![\frac{[cm^3] \frac{ft^3}{30.48^3 cm^3} }{[sec]} = \frac{[D][cm^2]}{[cP]} \frac{[atm]}{[cm]}](/images/math/8/5/c/85c147d9684a7c14364c8f4e919c56b1.png)
