Specific Weight

Specific weight is the weight per unit volume of a substance.

 

Specific Weight formulas

\(\large{ \gamma = \rho \; g }\)
\(\large{ \gamma = \frac{ p \;-\; p_s }{ NPSH \;-\; \frac{ v^2 }{ 2\; g } }  }\)	(net positive suction head)

Where:

\(\large{ \gamma }\)  (Greek symbol gamma) = specific weight

\(\large{ \rho }\)  (Greek symbol rho) = density

\(\large{ g }\) = gravitational acceleration

\(\large{ NPSH }\) = net positive suction head

\(\large{ p }\) = pressure

\(\large{ p_s }\) = vapor pressure

\(\large{ v }\) = velocity
