Pipeline Parameter

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:

\(\large{ \rho }\)  (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	\(\large{ft}\)	\(\large{m}\)
