1 Bar is Equal to How Many Atmospheric Pressure?
Atmospheric pressure is the pressure exerted by the weight of the air in the atmosphere. It is an important parameter in many fields, including physics, chemistry, and engineering. In this article, we will explore the relationship between the bar unit and atmospheric pressure.
What is a Bar?
A bar is a unit of pressure that is equal to 100,000 Pascals (Pa). It is a non-SI unit, but it is widely used in many fields, especially in engineering and physics. The bar unit is defined as the pressure that is equivalent to the weight of a column of mercury (Hg) that is 750 mm high at 0°C at standard gravity.
Atmospheric Pressure
Atmospheric pressure, also known as barometric pressure, is the pressure exerted by the weight of the atmosphere at sea level. The standard atmospheric pressure is defined as 1013.25 millibars (mbar) or 1 atm. This pressure is equivalent to the pressure exerted by a column of mercury that is 760 mm high at 0°C at standard gravity.
1 Bar is Equal to How Many Atmospheric Pressure?
Now, let's answer the question: 1 bar is equal to how many atmospheric pressure? To find the answer, we can convert 1 bar to mbar and then compare it to the standard atmospheric pressure.
1 bar = 100,000 Pa 1 mbar = 100 Pa So, 1 bar = 100,000 Pa / 100 Pa/mbar = 1000 mbar
Now, let's compare it to the standard atmospheric pressure:
1 atm = 1013.25 mbar So, 1 bar is approximately equal to 0.985 atm or 98.5% of the standard atmospheric pressure.
Conclusion
In conclusion, 1 bar is equal to approximately 0.985 atm or 98.5% of the standard atmospheric pressure. This conversion is important in many fields, including physics, chemistry, and engineering, where pressure units need to be converted between different systems.
