A U-shaped tube open to the air at both ends contains water. A quantity of oil of unknown density is slowly poured into the righ

nadezda [96]

Answer:

$\rho_o=600\ kg.m^{-3}$ is the density of the oil

Explanation:

Given:

height of oil column, $h_o=20\ cm$

oil column height that is more than the water column height in the other arm, $\delta h=8\ cm$

<u>Now from the given it is clear that the height of water column is:</u>

$h_w=h_o-\delta h$

$h_w=20-8$

$h_w=12\ cm$

Now according to the pressure balance condition of fluid columns:

Pressure due to water column = Pressure due to oil column

$P_w=P_o$

$\rho_w.g.h_w=\rho_o.g.h_o$

$1000\times 9.8\times 0.12=\rho_o\times 9.8\times 0.2$

$\rho_o=600\ kg.m^{-3}$ is the density of the oil
