Viscosity of water at atmospheric pressure - McCain correlation

Input(s)

S: Salinity (\% weight by solids)

$\mathrm{T}$: Temperature $(\mathrm{F})$

Output(s)

$\mu_{\mathrm{w} 1}$: Viscosity of water $(\mathrm{cP})$

Formula(s)

$$ \begin{aligned} \mu w 1= & \left(109.574-8.40564 * S+0.313314 * S^{\wedge} 2+8.72213 * 10^{\wedge}-3 * S^{\wedge} 3\right) \\ & * T^{\wedge}\left(-1.12166+2.63951 * 10^{-2} * S-6.79461 * 10^{-4} * S^{2}-5.47119\right. \\ & * 10^{-5} * S^{3}+1.55586 * 10^{-6} * S^{4} \end{aligned} $$
