when 2.7 kg of salt solution is poured into a cylindrical bottle, 200mm in diameter, the liquid level rise by 75mm. calculate the density and specific gravity
Explanations & Calculations
V=π.d24.h=2.356×10−3 m2\qquad\qquad \begin{aligned} \small V&=\small \pi .\frac{d^2}{4}. h\\ &=\small 2.356\times10^{-3}\,m^2 \end{aligned}V=π.4d2.h=2.356×10−3m2
ρ=mV=1146.0 kgm−3\qquad\qquad \begin{aligned} \small \rho &=\small \frac{m}{V}\\ &=\small 1146.0\,kg m^{-3} \end{aligned}ρ=Vm=1146.0kgm−3
r=ρLρw=1146.0 kgm−31000.0 kgm−3=1.146\qquad\qquad \begin{aligned} \small r&=\small \frac{\rho_L}{\rho_w}\\ &=\small \frac{1146.0\,kgm^{-3}}{1000.0\,kgm^{-3}}\\ &=\small 1.146 \end{aligned}r=ρwρL=1000.0kgm−31146.0kgm−3=1.146
