[tex]Dane:\\h = 25 \ cm = 0,25 \ m\\d = 1000\frac{kg}{m^{3}}\\g = 10\frac{N}{kg}\\Szukane:\\p = ?\\\\p = d\cdot g\cdot h\\\\p = 1000\frac{kg}{m^{3}}\cdot10\frac{N}{kg}\cdot0,25 \ m=2 \ 500 \ \frac{N}{m^{2}}\\\\\boxed{p = 2 \ 500 \ Pa = 2,5 \ kPa}\\\\(1 \ kPa = 1000 \ Pa)[/tex]
Odp. Szukane ciśnienie ma wartość 2,5 kPa.
