The aquarium, 20 cm x 40 cm in size and 50 cm in height, was completely filled with water. Find the modulus of water pressure to the bottom of the aquarium The density of water is considered constant throughout the depth and equal to 1000 kg / m3. The gravitational acceleration modulus is taken equal to 10 m / s2.
Р = F / S F = PS = pghS = pghab = 1000 * 10 * 0.5 * 0.2 * 0.4 = 400 Н
