WebbMeasuring Atmosphere Pressure. At sea level, the atmospheric pressure is about 101,300 Pa or 101,300 Nm-2. The instruments that measure atmospheric pressure are called barometers. One of the simple barometers is a mercury barometer. It consists of a glass tube 1 m long closed at one end. After filling it with mercury, it is inverted in a ... WebbHow many kPa is full vacuum? Vacuum is defined as air pressure below atmospheric pressure. The vacuum level is the difference in pressure between atmospheric pressure and pressure in the evacuated system: 0% vacuum = 760 torr = 14.7 psia = 29.92 inc mercury abs = 101.4 kPa abs. 50% vacuum = 380 torr = 7.3 psia = 15 inc mercury abs = …

Standard sea level air pressure is 1013 mb (millibars), which is the same as 29.92 inches of mercury or 14.7 pounds per square inch. What is the unit of pressure? Unit of pressure: pascal (Pa) Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P).
WebbThe height of the mercury column serves as an indicator of atmospheric pressure. At sea level and at a temperature of 0° Celsius (C), the height of the mercury column is approximately 30 inches, or 76 centimeters. This represents a pressure of approximately 14.7 psia. The 30-inch column is used as a reference standard. The standard atmosphere was originally defined as the pressure exerted by 760 mm of mercury at 0 °C (32 °F) and standard gravity (gn = 9.80665 m/s ). It was used as a reference condition for physical and chemical properties, and was implicit in the definition of the Celsius temperature scale, which defined 100 °C (212 °F) as the boiling point of water at this pressure. In 1954, the 10th General Conference on Weights and Measures (CGPM) adopted standard atmosphere for g…
