Ok, lets start with the basics:
let x = some distance [units = m]
let the area of some shape be a = x*x [units = m^2]
let the volume of some object be v = x*a [units = m^2]
we can see from above that the volume of an object contains information on its area.
So..
P [N/m^2]
rho [units = kg/m^3]
G [units = m/s^2]
h [units = m]
P = rho * G * h
N/m^2 = kg/m^3 * m/s^2 * m
N = kg*m/s^2 therefore:
N/m^2 = N/m^3 * m
canceling out m on top and bottom:
N/m^2 = N/m^2
The extra (* A / A) is not required. It reduces to 1. It is redundant to included this, as described above, because information on the objects area is already included within the volume.
Thank you for expanding the formulae from basic proofs. Actually this improves d
Thank you for showing the proofs from which this formulae derives. Actually this set of proofs improve the question. Personally I do and did realise how the formulae is derived from these basic proofs. What i was trying to impart to any enquiring mind is how the equation arrives at its final result and in nature takes no account of the millions of pounds of distributed atmospheric pressure, pressing down on the whole area of say the Atlantic Ocean, and because, and only because, of this equation has no effect on pressure at any depth. AS IF TO SAY THAT SOME `EXISTANCE` Who or Whatever has decreed " THIS IS HOW IT IS BECAUSE I SAY IT IS" Personally I wonder!
Lets work through an example here, involving water in the ocean. We will look at depths of 1m, 10m, 100m and 1,000m
rho sea water = ~1027kg/m^3
P = rho * G * H
1m
P = 1027kg/m^3 * 9.81m/s^2 * 1m = 10.07kPa_gage
10m
P = 1027kg/m^3 * 9.81m/s^2 * 10m = 100.7kPa_gage
100m
P = 1027kg/m^3 * 9.81m/s^2 * 100m = 1,007kPa_gage
1000m
P = 1027kg/m^3 * 9.81m/s^2 * 1000m = 10,007kPa_gage
The important part here is "gage". It means that all pressure is relative to the atmosphere. 1 ATM = 14.7psi or 101kPa. So if we wanted to find the pressure relative to a vacuum, "absolute", we simply add 101kPa to the number. After about 100m, atmospheric pressure only add 10% to the overall pressure. After 1000m, atmospheric pressure only adds 1% to the overall pressure. This is not to say that the atmospheric pressure is not great. 14.7 psi on your hand would be about the same as trying to hold up 235lb! (Its canceled on front and back so you don't notice). It most cases, water for example is about 1,000 times denser than air, pressures are indicated as "gage".
Pressure equals force divided by area.
pressure = force/area force = pressure x area area = force/pressure
kPa is pressure, how much area is the pressure acting on
If you mean in the ocean, approximately every 10 meters pressure increases by 1 bar. Assuming you want absolute pressure, at the surface you already have a pressure of approximately 1 bar - the atmospheric pressure. You can base your calculations on that.
big pressure comes from smaller surface areas therefore we need to find a side of the block with the smallest surface area. if you do 1m x 2m, that equals 2m squared and that is a large surface area. if you do 2m x 0.5, that equals 1m squared and that is STILL not small enough. HOWEVER if you do 0.5 x 1, that equals 0.5m squared and that is perfectly small enough.since pressure=force divided by area, we have to do 26000 (which is the force) divided by 0.5m squared which becomes 52000. therefore the final answer is 52,000 pascals.
Pressure equals force divided by area.
Force divided by pressure is equal to the area over which the force is applied. This relationship is defined by the formula: Area = Force / Pressure. It describes how the force distributed over a given area affects the pressure exerted on that area.
pressure = force/area force = pressure x area area = force/pressure
Fossil + pressure equals kerogen Kerogen + pressure equals bitumen Bitumen + pressure equal petroleum Petroleum + pressure equals gasoline
Yes. Pressure being voltage. Voltage divided by resistance equals current.
Pressure (P) is calculated by dividing the force (F) applied perpendicular to the surface by the area (A) over which the force is distributed. The equation for pressure is P = F/A.
Pressure equals the force exerted on a surface divided by the total area over which the force is exerted. It is typically measured in units such as pascals (Pa) or pounds per square inch (psi).
The Liquid will turn into gas. The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. If the liquid is open to the atmosphere (that is, not in a sealed vessel), it is not possible to sustain a pressure greater than the atmospheric pressure, because the vapor will simply expand until its pressure equals that of the atmosphere.
When the vapor pressure of a liquid equals the atmospheric pressure, the boiling point is reached, and the liquid boils. If the vapor pressure were to increase beyond the atmospheric pressure, the liquid would more readily vaporize, causing the boiling to continue or accelerate.
The term is "boiling point." At this temperature, liquid changes to vapor as its vapor pressure is equal to the atmospheric pressure.
No, force does not equal pressure times area. Force is the physical quantity that causes an object to accelerate, while pressure is the amount of force exerted per unit area. The relationship between force, pressure, and area is described by the formula: pressure = force/area.
Boiling point is when the liquids pressure equals the pressure of the atmosphere.
