The gage pressure in a liquid at a depth of 3 m is read to be 50 kpa. determine the gage pressure in the same liquid at a depth of 9 m.

The Gauge pressure at 9 meters depth is

Explanation:

Gauge pressure is the difference between absolute pressure and some reference pressure, most commonly atmospheric pressure. The increment in pressure caused by a static fluid is given by:

where is the density of the liquid,  g is the accleration due to gravity and d is the depth.

Now, we see that is linearly proportional to d, and we can assume that remains constant, because liquids are usually not compressible.

Given that the greater depth is simply 3 times the smaller depth:

at of depth will also be three times the gauge pressure at of depth.

We could also have calculated ny using:

and used this result to calculate the gauge pressure. These are both similar methods that yield the same result

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
