Pressure at Bottom of Flask: Liq. 1, 2 & 3

In summary, three different liquids with varying densities are poured into a cylinder in layers. The first liquid has a density of 6660 kg/m^3 and is poured to a depth of 70.8 cm. The second liquid has a density of 4995 kg/m^3 and is poured on top to a depth of 90 cm. Lastly, the third liquid with a density of 1369 kg/m^3 is poured on top of the second liquid to a depth of 68.5 cm. If the liquids do not mix, the pressure at the bottom of the flask can be calculated using the formula ρgh for each layer, but the atmospheric pressure should also be taken into account.

Liquid 1 with density = 6660 kg/m^3 is poured into cylinder to depth d1 = 70.8 cm; Liq. 2 with density 4995 kg/m^3 is poured on top to a depth of 90cm; and then liquid 3 (density of 1369 kg/m^3) is poured on top of liquid 2 to a depth of 68.5cm). Assuming none of the liquids mix at all what is the pressure at bottom of flask?

I used ρgh for each and added but this is wrong. Should I add the atmospheric pressure to the total?

Any help would be much appreciated..please?

Should I add the atmospheric pressure to each calculation or to the total (after adding each (densityxgxh calculation)?

What is pressure at the bottom of a flask?

The pressure at the bottom of a flask is the force per unit area exerted by the liquid inside the flask on the bottom surface of the flask.

How is pressure at the bottom of a flask measured?

Pressure at the bottom of a flask can be measured using a pressure gauge or by using the height of the liquid column in the flask and the density of the liquid.

What factors affect pressure at the bottom of a flask?

The pressure at the bottom of a flask is affected by the density of the liquid, the depth of the liquid, and the acceleration due to gravity.

Why is pressure at the bottom of a flask important to consider?

Pressure at the bottom of a flask is important to consider because it can impact the stability and integrity of the flask, especially if the liquid inside is under high pressure.

How does pressure at the bottom of a flask change with different liquids?

The pressure at the bottom of a flask can vary depending on the density and depth of the liquid. Liquids with higher density and deeper depths will exert more pressure at the bottom of the flask compared to liquids with lower density and shallower depths.
