Question

A tank 5 metre high is filled with water to 3 then is filled to the top with oil of density 0.85 gram per centimetre cube .The pressure at the bottom of the tank due to this liquid is_______​

Answer 1

Answer:

Given that,

Total height of tank = 5m

Density of water ρ

1

=1g/cm

3

Density of oil ρ

2

=0.85g/cm

3

We know that,

Half tank filled with water and half tank filled with oil.

So, h

1

=h

2

=2.5m=250cm

The pressure at the bottom of the tank is

P=h

1

ρ

1

g+h

2

ρ

2

g

P=g(250×1+250×0.85)

P=462.5g g/cm
