What is the depth of a point below the water surface in the sea, where pressure intensity is 1.006 MN/ m2?

(Specific gravity of seawater is 1.025)

[A] 60 m
[B] 80 m
[C] 100 m
[D] 120 m

ANSWER= [B] 80 m

Detailed Solution for Civil Engineering Exam

P_b = γ_sea•h = 1.006 * 10⁶ N/m²

h = (1.006 * 10⁶)/γ_sea

h = [(1.006 * 10⁶ N/m² )/(1.25 * 9810 N/m³ ) ] = 82.04 m

h = 80 m
