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

Answer:

10⁴ Pa

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
