Question

the volume of a water tank is 5m×4m×2m. If the tank is half filled with water. calculate the pressure exerted at the bottom of the tank​

Answer 1

10⁴ Pa

Step-by-step explanation:

• Volume = 5m * 4m * 2m

When the tank is half filled ,

• Volume = 5m * 4m * 1m = 20m³

Also we know that ,

• Density of water = 10³ kg/ m³

`\longrightarrow` Density = Mass/Volume

`\longrightarrow` 10³ kg/m³ = m/20m³

`\longrightarrow` m = 2 * 10⁴ kg

So that ,

`\longrightarrow` Weight = mg

`\longrightarrow` F = 2*10⁴ × 10 N

`\longrightarrow` F = 2 * 10⁵ N

And ,

`\longrightarrow` Pressure = Force/Area

`\longrightarrow` P = 2 *10⁵/ 5 * 4 Pa

`\longrightarrow` P = 10⁴ Pa
