Answer:
The pressure at the bottom of the water layer is [tex]1.25\times10^{5}\ Pa[/tex]
Explanation:
Given that,
Oil layer = 120 cm
Water layer = 140 cm
We need to calculate the pressure at the bottom of the water layer
Using formula of pressure
[tex]P_{atm}=P_{atm}+P_{oil}+P_{w}[/tex]
[tex]P_{ab}=p_{atm}+\rho_{oil} gh+\rho_{w} gh[/tex]
Put the value into the formula
[tex]P_{ab}=1.013\times10^{5}+881\times9.8\times1.2+1000\times9.8\times1.4[/tex]
[tex]P_{ab}=125380.56\ Pa[/tex]
[tex]P_{ab}=1.25\times10^{5}\ Pa[/tex]
Hence, The pressure at the bottom of the water layer is [tex]1.25\times10^{5}\ Pa[/tex]
