ASTM on Data Normalisation

$\operatorname {erfc} (x)={\frac {2}{\sqrt {\pi }}}\int _{x}^{\infty }e^{-t^{2}}\,dt={\frac {e^{-x^{2}}}{x{\sqrt {\pi }}}}\sum _{n=0}^{\infty }(-1)^{n}{\frac {(2n)!}{n!(2x)^{2n}}}$ $\operatorname {SpecificFlux} ={\frac {Flux\times TCF}{NDP}}$

Where: $\operatorname {TCF} =e^{x}$ $x=u\left({\frac {1}{T+273}}-{\frac {1}{298}}\right)$ NDP = Net Driving Pressure $x=u\left({\frac {1}{T+273}}-{\frac {1}{298}}\right)$
