Question
A submarine is at depth 100 m. If atmospheric pressure = 10⁵ Pa, seawater density = 1025 kg/m³, g = 10 m/s², gauge pressure on hull is:
- A10.25×10⁵ Pa
- B1.025×10⁶ Pa
- C1.025 MPa
- DAll of the aboveCorrect
Correct answer
All of the above
Explanation
Gauge P = ρgh = 1025×10×100 = 1.025×10⁶ Pa = 10.25 atm. All three options express the same value.
