­5 Partial Pressure Example: Detailed Explanations


In this article ”Partial pressure example” is discuss and also gave a brief description about partial pressure example. From the law of Dalton’s we can get a clear idea about partial pressure example. 

6+ partial pressure examples and their detailed explanations are mention in below,

  1. Fire extinguisher
  2. Aerosol cans
  3. Opening soda cans
  4. Flying of jet aeroplanes
  5. Pressure is calculated of a dry gas
  6. Examine patient’s blood

Fire extinguisher:

The common example of partial pressure is fire extinguisher which is device used for as an active fire protection. The fire extinguisher device mainly used for to control small or extinguish fire. When fire extinguisher is uses in the field before that we should have clear concept about how it should to use and which type suitable in the particular field.

A fire extinguisher is containing a long cylinder. At the top the long cylinder an operating lever is placed. A tube which is filled with carbon dioxide is present inside the cylinder and around it surrounding amount of water is present for this reason pressure is create around the tube of carbon dioxide.

A siphon tube is present in the cylinder of fire extinguisher. The siphon tube is going in the horizontally of the cylinder and open with the water near the section of the bottom. In other side of ending a chamber is placed which have mechanism of spring and connected with discharge valve of the carbon dioxide tube.

The mixture of carbon dioxide and water does not contain the whole cylinder. Head space is present in the cylinder for this reason the area of the cylinder fill with air. The operating lever when stooping that time the spring mechanism is working and discharge valve is open which is situated at top section of carbon dioxide tube. At the stage when discharge valve is open dioxide comes at the area of head space and water is exerted by pressure. The mixture is comes out by the help of siphon tube and fire extinguisher start to working.

Aerosol cans:

An Aerosol cans structure is most of similar to fire extinguishers. Inside the Aerosol cans a tube is present and it also contains the spring mechanism as same as fire extinguisher and comes out with help of a tube. The main difference between the aerosol cans and fire extinguisher is instead of gas liquid propellant is present.

Opening soda cans:

Inside a soda can carbon monoxide is present among them maximum are dissolved in the drink by itself.  But some carbonated soda takes a space for this particular reason difference is appear in the volume of the jar and volume of the drink of soda.

In the plant of the blotting carbon dioxide is added in the soda can which should carry high pressure to create a head space to confirm that more amount of carbon dioxide should be absorb in the soda by itself.

Flying of jet aeroplanes:

The jet aeroplanes works in the principle of partial pressure. With the help of propeller powered aircraft the maximum efficiency can achieve the jet planes. The response of the jet planes is not too higher. 

When the jet discharge gas ignites back the jet aeroplanes can move forward itself.

Pressure is calculated of a dry gas:

In a dry gas with the help of partial pressure the total amount of pressure can be calculated.

Examine patient’s blood:

For surviving oxygen is needed for human body. Humans are exposed constantly changes in Blood Pressure, that can be naturally or artificially, for this particular reason pressure inspired oxygen and it is indirectly proportional to reduction among exposed to normobaric hypoxia or hypobaric.

Frequent Asked Question:-

Question:  Explain Dalton’s law where partial pressure example works.

Solution: From the law of Dalton’s we get a clear concept about the partial pressure of a matter.

The law of Dalton of a partial pressure is explain as, the total amount of pressure is exerted by externally by a compound of gasses substance is equal to total amount of partial pressure which is exerted by each every particular gas in the compound.

Suppose in a jar two types of gas carbon monoxide and oxygen is present and makes a mixture. Then the total amount of pressure exerted in the compound gas of car monoxide and oxygen is sum is equal to their individual partial pressure which is exerted by gas car monoxide and gas oxygen.

Formula of Dalton’s law:

The formula of Dalton’s law can be written as,

Where,

Ptotal = The total amount of pressure which is exerted by the compound of gas

R = Universal gas constant

T = Temperature in Kelvin

V = Volume of the matter

Question:  Which factors are affected the partial pressure and how they are related to each other describe it?

Solution: The factors which are affected the partial pressure is listed below,

  1. Temperature
  2. Pressure
  3. Total amount of gas which is measure by mole number

Temperature:

The relation between the temperate and partial pressure is directly proportional each other. Means if the rate of temperature is increases of a matter for this case the partial pressure is also increases, and if the rate of temperature is decreases of a matter for this case the partial pressure is decreases.

Pressure:

The relation between the pressure and partial pressure is indirectly proportional to each other. Means if the rate of pressure is increases of a matter for this case the partial pressure is decreases, and if the rate of temperature is decreases of a matter for this case the partial pressure is increases.

Total amount of gas which is measure by mole number:

The relation between the total amount of gas which is measure by mole number and partial pressure is directly proportional each other. Means if the rate of total amount of gas which is measure by mole number is increases of a matter for this case the partial pressure is also increases, and if the rate of total amount of gas which is measure by mole number is decreases of a matter for this case the partial pressure is decreases.
