Question

sewage treatment plant: a sewage treatment plant has a 3 - meter - deep sedimentation tank. calculate the hydrostatic pressure at its base. (sewage density = 1050 kg/m³) p = i pa question 10 1 pts foundation in wet soil: determine the hydrostatic pressure on a foundation 6 meters below the water table (water density = 1000 kg/m³)

Explanation:

Step1: Recall hydrostatic pressure formula

The formula for hydrostatic pressure is $P =
ho gh$, where $
ho$ is the density of the fluid, $g$ is the acceleration due to gravity ($g = 9.8\ m/s^{2}$), and $h$ is the depth.

Step2: Substitute given values

We have $
ho= 1050\ kg/m^{3}$, $g = 9.8\ m/s^{2}$, and $h = 3\ m$. Substituting these into the formula gives $P=1050\times9.8\times3$.

Step3: Calculate the result

$P = 1050\times9.8\times3=1050\times29.4 = 30870\ Pa$.

Answer:

$30870$
