Question

I think 2 metre high is half filled with water and then feel to talk with oil of density 0.80 gram per CC what is the pressure at the bottom of the tank due to this liquids​

Answer 1

Answer:

pressure at the bottom of the tank = density of liquid *height *acc. due to gravity

pressure at the bottom of the tank = density of liquid *height *acc. due to gravity=2*80*10(roughly)

=1600nper m^2

Answer 2

Explanation:

Solution :-

Given :-

h = 2 m

Density of oil, ρ(o) = 0.80 g/cc

= 0.80 × 10³ kg/m³

Density of water, ρ(w) = 10³ kg/m³

Mean density, say ρ = ρ(o) + ρ(w)/2

= 0.80 × 10³ + 1 × 10³/2

= 0.90 × 10³ kg/m³

Therefore, Pressure at the bottom,

P = hρg

P = 2 × 0.90 × 10³ × 10

P = 1.80 × 10⁴ Nm⁻²

Hence, the pressure at the bottom of tank due to these liquids is 1.80 × 10⁴ Nm⁻².
