Answer:
The pressure difference across hatch of the submarine is 3217.68 kpa.
Explanation:
Gauge pressure is the pressure above the atmospheric pressure. If we consider gauge pressure for finding pressure differential then no need to consider atmospheric pressure as they will cancel out. According to hydrostatic law, pressure varies in the z direction only.
Given:
Height of the hatch is 320 m
Surface gravity of the sea water is 1.025.
Density of water 1000 kg/m³.
Calculation:
Step1
Density of sea water is calculated as follows:
![S.G=\frac{\rho_{sw}}{\rho_{w}}](https://tex.z-dn.net/?f=S.G%3D%5Cfrac%7B%5Crho_%7Bsw%7D%7D%7B%5Crho_%7Bw%7D%7D)
Here, density of sea water is
, surface gravity is S.G and density of water is
.
Substitute all the values in the above equation as follows:
![S.G=\frac{\rho_{sw}}{\rho_{w}}](https://tex.z-dn.net/?f=S.G%3D%5Cfrac%7B%5Crho_%7Bsw%7D%7D%7B%5Crho_%7Bw%7D%7D)
![1.025=\frac{\rho_{sw}}{1000}](https://tex.z-dn.net/?f=1.025%3D%5Cfrac%7B%5Crho_%7Bsw%7D%7D%7B1000%7D)
kg/m³.
Step2
Difference in pressure is calculated as follows:
![\bigtriangleup p=rho_{sw}gh](https://tex.z-dn.net/?f=%5Cbigtriangleup%20p%3Drho_%7Bsw%7Dgh)
![\bigtriangleup p=1025\times9.81\times320](https://tex.z-dn.net/?f=%5Cbigtriangleup%20p%3D1025%5Ctimes9.81%5Ctimes320)
pa.
Or
![\bigtriangleup p=(3217680pa)(\frac{1kpa}{100pa})](https://tex.z-dn.net/?f=%5Cbigtriangleup%20p%3D%283217680pa%29%28%5Cfrac%7B1kpa%7D%7B100pa%7D%29)
kpa.
Thus, the pressure difference across hatch of the submarine is 3217.68 kpa.
