Pipeline Parameter

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Pipeline parameter, abbreviated as \(\rho\), a dimensionless number, is proportional to maximum water hammer pressure rise and static pressure.

 

Pipeline Parameter formula

\(\large{ \rho = \frac {v\;v_i}  {2\;g\;h_s}   }\)   

Where:

 Units English Metric
\(\large{ \rho }\)  (Greek symbol rho) =  pipeline parameter \(\large{dimensionless}\)
\(\large{ g }\) = gravitational acceleration  \(\large{\frac{ft}{sec^2}}\) \(\large{\frac{m}{s^2}}\)
\(\large{ v_i }\) = initial velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ v }\) = wave velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ h_s }\) = static head \(\large{ft}\) \(\large{m}\)
