ENGR217 2024 Q A1(b) (data only)[PARTIAL] Left out: The pump head-rise calculation (manometer plus Bernoulli, Lectures 2 and W3-4).

A pumped liquid has specific gravity $S_1 = 0.82$ and the manometer fluid is mercury with $S_2 = 13.6$ . State what "specific gravity" means in the current module's notation, and find the density and specific weight of both fluids.

rho_1 =kg/m^3

gamma_1 =N/m^3

rho_2 =kg/m^3

gamma_2 =N/m^3

Formulas it uses

Relative density
$RD = \frac{\rho_{fluid}}{\rho_{water}}$
Specific weight
$\gamma = \frac{m g}{V} = \rho g$
