SUMMARY

The discussion focuses on calculating the absolute pressure at the bottom of a container filled with seawater and an oil layer. Given the oil density of 0.75 x 10^3 kg/m^3 and the height of the water column at 55 cm, the pressure is calculated using the formula p = pa + pgh. The specific gravity of seawater is noted as approximately 1.025, which is essential for determining the pressure exerted by the water column.

PREREQUISITES
  • Understanding of fluid mechanics principles
  • Familiarity with pressure calculations in fluids
  • Knowledge of specific gravity and density concepts
  • Ability to apply the hydrostatic pressure formula p = pa + pgh
NEXT STEPS
  • Research hydrostatic pressure calculations in fluids
  • Learn about specific gravity and its applications in fluid dynamics
  • Explore the properties of seawater and its density variations
  • Study the effects of oil spills on marine environments and fluid behavior
USEFUL FOR

Students studying fluid mechanics, environmental scientists analyzing oil spills, and engineers working with fluid pressure systems.

Homework Statement


In a sample of seawater taken from an oil spill, an oil layer 4.0 cm thich floats on 55 cm of water. If the density of the oil is 0.75 x 10^3 kg/m^3, what is the absolute pressure on the bottom of the container.

p= 0.75x10^3 kg/m^3
g = 9.8m/s^2
h=.55m
p=?
pa = density of seawater??

Homework Equations


p=pa+ pgh


The Attempt at a Solution



p = pa+ (0.75x10^3 kg/m^3)(9.8m/s^2)(.55m)

4 cm =??:confused:

sg of sea water about 1.025
you need to add all pressures, from p=density*g*h of the two columns plus ambient.
