Answer 2

It looks like you want to calculate the height (h) of a fluid column with a density (ρ) of 1000 kg/m³ when subjected to a pressure difference (ΔP) resulting in a density of 900 kg/m³. You are given the pressure difference (ΔP) as 0.2 meters of fluid column.

To find the height (h) of the fluid column, you can use the hydrostatic pressure formula:

ΔP = ρ * g * h

Where:

• ΔP is the pressure difference (0.2 m in this case).
• ρ is the density of the fluid.
• g is the acceleration due to gravity (approximately 9.81 m/s²).
• h is the height of the fluid column (which we want to find).

Given: ρ1 = 1000 kg/m³ (density at the bottom) ρ2 = 900 kg/m³ (density at the top) ΔP = 0.2 m

Let's calculate h:

First, find the pressure difference (ΔP) due to the density difference: ΔP = ρ1 * g * h - ρ2 * g * h

0.2 m = (1000 kg/m³ - 900 kg/m³) * 9.81 m/s² * h

Now, solve for h:

0.2 m = (100 kg/m³) * 9.81 m/s² * h

h = 0.2 m / (100 kg/m³ * 9.81 m/s²)

h ≈ 0.0203 meters

So, the height (h) of the fluid column is approximately 0.0203 meters, or 2.03 centimeters.
