Pressure at a certain depth below ocean is 1.4 MPa. What is the depth approximately?

Pressure at a certain depth below ocean is 1.4 MPa. What is the depth approximately? Correct Answer 140 m

Concept:

Pressure due to 'h' m column of fluid (P) = ρgh

Calculation:

Given:

ρ = 1000 kg/m3, g = 10 m/s2, P = 1.4 MPa = 1.4 ×106 N/m2

P = ρgh

1.4 × 106 = 1000 × 10 × h

∴ h = 140 m

Hence depth is approximately 140 m.
