Reynolds Number for Liquid Formula

\( Re \;=\; 92.1\; SG \; Q \;/\; d \; \eta \)     (Reynolds Number)

\( SG \;=\; Re \; d \; \eta  \;/\; 92.1\; Q \)

\( Q \;=\;   Re \; d \; \eta  \;/\; 92.1\; SG  \)

\( d \;=\; 92.1\; SG \; Q \;/\; Re \; \eta \)

\( \eta \;=\; 92.1\; SG \; Q \;/\; Re \; d \)

Symbol English Metric
\( Re \) = Reynolds Number \( dimensionless \) \( dimensionless \)
\( SG \) = Liquid Specific Gravity Relative to Water (water = 1) \( dimensionless \) \( dimensionless \)
\( Q \) = Liquid Flow Rate \(ft^3\;/\;sec\) \(m^3\;/\;s\)
\( d \) = Inside Diameter of Pipe \( in\) \( mm \)
\( \eta \)  (Greek symbol eta)  = Liquid Viscosity \(lbf - sec\;/\;ft^2\) \(Pa-s\)
