Marks: +1, -0

An open tank contains water up to a depth of 2 m and above it an oil of specific gravity 0.9 for a depth of 1 m. Find the pressure intensity at the interface of the two liquids.

7829 N/m $^2$
9829 N/m $^2$
8829 N/m $^2$
6829 N/m $^2$

Solution:

S_\oil = 0.9, ρ_\oil = 900 kg\/m^3, h_\oil = 1 m,

h_\water = 2 m

P = ρ_\oil × g × h_\oil

∴ 0.9 × 1000 × 9.81 × 1 = 8829
