Calculate the pressure experienced by the sensor ?

[Colin19]

Homework Statement

A sensor is at rest in a fuel tank , it is at a depth of 0.34m
and the fuel has a specific gravity of 0.7 .
Calculate the pressure experienced by the sensor ?

Homework Equations

I guess Pressure = force/area

The Attempt at a Solution

I considered gravity as the force
And depth as the area
to apply it on the stated equation
Using some site calculator
Result was = 2.0588235294118 Newton/meter^2

After some revision , I think it's 0.34x0.7x9.81 = p ?

Actually it's after asking a friend

 

[Colin19]

I'm totally clueless what is the logic behind this and what is the correct method to solve

Ok , Thanks I found the answer
Equation :
Used with liquid columns of constant density or at a depth within a substance (example: pressure at 20 km depth in the Earth).
p = Height x density x gravity
where:
P is Pressure
g is gravity at the surface of overlaying material
ρ is density of liquid or overlaying material
h is height of liquid or depth within a substance
...
Got it

I feel that this thread is pointless is it possible to delete it . \ :
