A container is filled to a depth of 18.0 cm with water On top of the water floats a 33.0-cm thick layer of oil with specific gravity 0.800 What is the absolute pressure at the bottom of the container?

The pressure will be the sum of pressures of oil and water:
p = rowater g hwater + rooil g hoil
Specific gravity of 0.8 of oil means it's 0.8 times as dense as water:
rooil = 0.8 rowater
Pressure will be then:
p = g (rowater hwater + 0.8 rowater hoil), or numerically:
p = 4355.64 Pa

How does specific gravity effect head pressure?
Head pressure=specific gravity*1000*gravity*height. Therefore if specific gravity is increased head pressure will increase.
What is the specific gravity of magnetite?
There is no such thing as a specific gravity for any element.
In which direction is pressure exerted in a fluid at rest?
If its in a container, pressure is downward and outward due to gravity and confinement respectively. If its on a flat surface without confinement, the pressure is exerted downwards on the surface and the boundaries are held by a combination of adhesion and cohesion.
What is the velocity of the container from which liquid is coming out from hole at its bottom?
This question does not provide enough information on the relevant parameters to even attempt an answer. One would assume that if the hole is at the bottom of the container (and not on the side at the bottom) and the liquid is coming out of the hole only due to gravity that the the container would remain stationary. If there is internal pressure in the container, then the initial pressure becomes important as does the time since the water began to flow. If the hole is on the side of the container, then friction between the container and the surface it is resting on become significant. If the container is not circular in cross section, then the location of the hole along the side helps determine whether the container moves laterally or spins.
What fluid has the biggest specific gravity?
Oil has the highest specific gravity. Water has the second.
How does specific gravity effect head pressure?
Head pressure=specific gravity*1000*gravity*height. Therefore if specific gravity is increased head pressure will increase.
What is the formula for absolute pressure?
but i think the absolute pressure is P(pressure)/{p(density)*g(gravity)}
What is the meaning of absolute specific gravity?

Define specific gravity?
The specific gravity is the ratio between the density of a material and the density of water, at a given temperature and pressure.
What is the specific gravity of gasoline in a gaseous state?
Specific gravity, (similar to density) has no meaning for a gas, since the density varies with pressure and temperature.
Does absolute pressure in a liquid of constant density double when the depth is doubled?
No, the absolute pressure in a liquid of constant density would not double in this situation. This is because the atmospheric pressure is an independent variable, so it will keep the absolute pressure from doubling.
What are 6 different properties of fluids?
Density, Viscosjty, pressure, specific weight, specific gravity, specific volume
What is the physical property of minerals that is defined as the average weight per unit volume compared to the same volume of water is called?
This is called the Specific Gravity of a substance. The density of the material divided by the density of water yields the specific gravity, a specific gravity greater than 1 indicates the substance will sink in water. A specific gravity less than 1 indicates the substance will float in water. Because the units expressed in density cancel each other out specific gravity has no unit dimensions. example: substance 1 has a density of 12 grams per ml water has a density of 1 g/ml then substance 1 has a specific gravity of 12. 12 g/ml / 1 g/ml = 12 *note: for true specific gravity the atmospheric pressure, absolute , and the temperature absolute of both the sample material and the water must be indicated in the calculations as well. ** for gasses the constant or reference medium is air
The ratio of the weight of a given volume of a substance in a vacuum at a given temperature to the weight of an equal volume of water in a vacuum at a given temperature is known as?
This ratio is called the specific gravity.
Does specific gravity has units?
- The specific weight is the weight of a known volume of material at a given temperature and pressure; the unit of measure is kN/m3. - But if you think to relative density: Relative density (specific gravity) is the ratio between the density of the material to be tested and the density of water, at a given temperature and pressure; consequently no unit of measure for this ratio.
The volume of a gas is the force of its outward push divided by the area of the walls of the container True or False And what's the answer?
The gas's pressure is defined as the outward push against the walls of its container, though gravity contributes to this somewhat. More importantly, this pressure can cause the gases to condense into liquids if it's high enough.
Hi I Know the specific gravity of a gas at NPT How can you calculate the specific gravity of tha gas at 400 bar pressure and ambient temperature?
Is this a school question that you simply don't know the answer to?
