Calculate the pressure experienced by the sensor ?

In summary, the conversation discusses calculating the pressure experienced by a sensor at rest in a fuel tank at a depth of 0.34m with a specific gravity of 0.7. The suggested equation for calculating pressure is P = h x ρ x g, where P is pressure, h is height or depth, ρ is density, and g is gravity. After some discussion and revision, the correct method is determined and the answer is found. The thread ends with a request to delete it.

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 calculater
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
 
  • #4
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

FAQ: Calculate the pressure experienced by the sensor ?

What is pressure and how is it measured?

Pressure is the force exerted by a substance on a unit area. It can be measured using a pressure sensor, which typically measures the force applied on a small area or the change in volume of a confined gas.

What factors affect the pressure experienced by a sensor?

The pressure experienced by a sensor can be affected by various factors such as the amount of force applied, the area over which the force is distributed, the type of substance exerting the force, and the sensitivity of the sensor.

How is the pressure calculated using a sensor?

The pressure can be calculated by dividing the force applied on the sensor by the area over which it is distributed. This gives the pressure in units of force per unit area (e.g. N/m2 or Pa).

What are the units of pressure and how are they converted?

The SI unit of pressure is Pascal (Pa), but other commonly used units include atmospheres (atm), pounds per square inch (psi), and millibars (mbar). These units can be converted using conversion factors, which can be found online or in a physics reference book.

How accurate are pressure sensors and how can their accuracy be improved?

The accuracy of pressure sensors can vary depending on the type and quality of the sensor. Generally, a higher quality sensor will have a lower margin of error. The accuracy can also be improved by calibrating the sensor regularly and ensuring it is used within its specified range of pressure and temperature.
