Question

a tank of 5 M height is half filled with water and then filled to the top with oil of density is 0.85 grams per centimetre cube then density of total mixture release​

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
