What are the different types of pressure feet?

water for example.absolute pressure; gauge pressure; atmospheric pressure


What are the difference between room pressure and absolete pressure?

standard atmospheric pressure at sea level is 14.73 psi Absolute pressure is a gauge plus atmospheric pressure. The gauge being something that you are detecting.. i.e hot water tank.


What is atmospheric humidity?

Atmospheric humidity is defined as the amount of pressure of water vapor in an air to water mixture. This will be influenced by the temperature at a given time.


State and explain how the boiling point of water will change if the atmospheric pressure falls?

Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).

What effcet does altitude have on boiling point of water?

Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.


What happens when pressure greater than atmospheric pressure is applied to pure water or a solution?

If a pressure greater than atmospheric pressure is applied to a solution or pure water, its water potential increases


Why does water boil when the vapor pressure is equal to atmospheric pressure?

Because while atmospheric pressure is the greater of the two the vapour pressure of the water can not spontaneously form bubbles (ie boil).


Difference between bar and barg?

The 'g' added on to bar means 'gauge', as opposed to bara, meaning 'absolute'. The 'zero' of a normal gauge is normally set at atmospheric pressure (things like tire pressure gauges, water gauges etc.) These gauges will read as "10 bar" but really mean that the absolute pressure is 10 bar + atmospheric pressure (~1.01325 bar). Some gauges however are absolute gauges. These might include weather gauges, or gauges on closed processes. bara = barg + atmospheric pressure


What is the pressure of water at a depth of 10000 ft?

Roughly 4.3 psig or 29 kPag on Earth near sea level ("g" meaning gauge pressure, additional to atmospheric pressure).


What is cause of atmospheric pressure?

Just as water pressure is caused by the weight of water, atmospheric pressure is caused by the weight of the air. Pg. 126 Conceptual Physical Science 4th Edition.


What is potential pressure?

the pressure of water measured relative to the atmospheric pressure at the same elevation.
