Answer:
The pressure at the bottom of the tank is 58kN/m².
Explanation:
The pressure at the bottom of the tank is calculated as,
(1)
Where,
P=pressure at the base of the tank
ρw=density of water
ρo=density of oil
hw=height up to which water is present in the tank
ho=height up to which oil is present in the tank
g=acceleration due to gravity=10m/s²
From the question we have,
Total height of the tank(H)=6m
hw=4m
ho=2m
The relative density of oil is =0.9
The relative density(R.D) of oil is given as,
So,
(∵ρw=1000kg/m³)
By substituting the required values in equation (1) we get;
Hence, the pressure at the bottom of the tank is 58kN/m².
