Answer:
0.8 m
Step-by-step explanation:
P = P₀ + ρgh
where P is the pressure at the bottom point,
P₀ is the pressure at the top point,
ρ is the density of the fluid,
g is the acceleration due to gravity,
and h is the distance between the points.
At the surface, the pressure is 0 Pa gauge. Therefore:
12000 = 0 + (1000) (10) (2.0−h)
12000 = 10000 (2.0−h)
2.0−h = 1.2
h = 0.8
