Flow Rate

Standard to Actual: Gas Flow

​ ${\frac{{\mathrm{ft}}^3}{\mathrm{hr}}}_{\left[S\right]}={\frac{{\mathrm{ft}}^3}{\mathrm{hr}}}_{\left[A\right]}\times \frac{520}{T+460}\times \frac{P+14.7}{14.7}$

​$$\begin{gathered} T=\text{Temperature}[°\mathrm{F]} \\ P=\text{Pressure}\mathrm{[psig]} \end{gathered}$$

Standard to Actual: Liquid Flow

 

 

Pressure

​$P=\frac{\mathrm{SG}\times H}{2.31}$

 

Viscosity

​$\gamma =\frac{\Phi }{\mathrm{SG}}$

​$$\begin{gathered} \gamma =\text{Kinematic Viscosity}\mathrm{[cSt]} \\ \Phi =\text{Dynamic Viscosity}\mathrm{[cP]} \\ \mathrm{SG}=\text{Specific Gravity} \end{gathered}$$

 

API

​ $\mathrm{API}=\left(\frac{141.5}{\mathrm{SG}}\right)-131.5$
