Korolek [52]

Answer:

$\Delta P = 98.07\,Pa$

Explanation:

The difference between top and bottom surfaces is computed by the following hydrostatic equivalence:

$\Delta P = \rho_{w}\cdot g \cdot \Delta h$

$\Delta P = \left(1000\,\frac{kg}{m^{3}} \right)\cdot \left(9.807\,\frac{m}{s^{2}} \right)\cdot (0.01\,m)$

$\Delta P = 98.07\,Pa$
