#37- An aquarium with a base of 35 cm by 80cm has 55l of water in it. Whats the pressure of the bottom of the tank?

Ultimate Strength of Materials Tensile Strength (N/m2) 1.7× 108 5.0 × 108 2.0 x 108 1.2 x 108 Compressive Strength (N/m2) 5.5 × 108 5.0 x 10 2.0 x 10 1.5 × 108 8.0 × 107 3.5 x 107 2 × 107 Material ron Steel Aluminum Bon Marble Brick Concrete l x 10 2×106

Explanation / Answer

#25 insufficient data to answer. Pictures are not provided.

#37:

pressure, P = rho*g*H

the dentsity of water, rho = 1000 kg/m^3

Volume = Area*Height

given, Volume = 55 L = 0.055 m^3

Area = 35*10^-2 * 80*10^-2 = 0.28 m^2

Height = Volume/Area = 0.196 m

P = 1000 kg/m^3 * 9.81 ms^2 * 0.196 m

Pressure of the bottom of the tank, P = 1922.8 Pa
