Answer to Question #301442 in Mechanics | Relativity for Jhonard

Question

Calculate the specific weight, specific mass, specific volume and specific gravity of a liquid having a volume of 5 cubic meters and its weight is 35 kilo newton

Answer 1

Answer

Weight of liquid

$W=35KN$

So it's mass becomes

$M=\frac{W}{g}\\=\frac{35000}{9.81}\\=3567.8Kg$

Volume

$V=5m^3$

So

$Specific \space weight \\\gamma=\frac{W}{V}\\=\frac{35000}{5}\\=7000N/m^3$

Specific mass

M=3567.8Kg

Density

$\rho =\frac{M}{V}\\=\frac{3567.8}{5}\\=711.54Kg/m^3$

Specific volume

$v=\frac{V}{M}\\=\frac{5}{3567.8}\\=0.0014m^3/kg$

Specific gravity

$Sg=\frac{\gamma}{\gamma_{at 4°C}}\\=\frac{7.000}{9.81}\\=0.71$
