A container is filled to a depth of 19.0 cm with water. On top of the water floats a 31.0-cm-thick layer of oil with specific gravity 0.600. What is the absolute pressure at the bottom of the container?

Respuesta :

Answer:

Absolute pressure of the oil will be 102822.8 Pa  

Explanation:

We have given height h = 31 cm = 0.31 m

Acceleration due to gravity [tex]g=9.8m/sec^2[/tex]

Specific gravity of oil = 0.600

So density of oil [tex]\rho =0.6\times 1000=600kg/m^3[/tex]

We know that absolute pressure is given by [tex]P=P_0+\rho gh[/tex], here [tex]P_0=1.01\times 10^5Pa[/tex]

So absolute pressure will be equal to [tex]P=1.01\times 10^5+600\times 9.8\times 0.31=102822.8Pa[/tex]

So absolute pressure of the oil will be 102822.8 Pa
