A container is filled to a depth of 22.0 cm with water. On top of the water floats a 33.0-cm-thick layer of oil with specific gravity 0.600. What is the absolute pressure at the bottom of the container?

Thank you for the opportunity to help you with your question!

PA=Patm+density*g*h

oil's specific gravity is 0.6

density of oil=0.6*1000kg/m^3=600kg/m^3

PA=1.103*10^5+600*9.8*0.33=112240.4Pa

PB=112240.4Pa+1000*9.8*0.22=114396.4 Pa


Please let me know if you need any clarification. I'm always happy to answer your questions.

wrong answer you are not smar

....hold up let me try to fix it

Pabs = Patm + ρw*g*Dw + ρo*g*Do = 1.013E5 + 1000*9.8*.22 + 600*9.8*0.33

Pabs = 105396.4 Pa=1.05E5 Pa

what about this time?

what is that 1.05E5 ??????


Jun 11th, 2015

it means 1.05*10^5, they are the same thing
