### Barometers - Fisher Sci

Barometers are instruments that measure the pressure of air in a specific environment; barometer measurements are used to forecast weather and measure altitude.Atmospheric pressure also depends on the planets mass,its surface radius,the gas concentrations and composition,and the gases vertical distribution in the atmosphere.Barometric Pressure - an overview ScienceDirect TopicsThe barometric pressure in a deep shaft increases by one inch of Hg for every 1000 ft depth.Thus in a 3000 ft deep shaft,the surface air pressure of 30 in.of Hg will increase by 3 in.of Hg at the shaft bottom.Because volume of air is directly proportional to pressure (refer to Chapter 1 ),the air will expand by 10% in the return shaft of Bubble in a Lake Collection of Solved Problemsp 1 V 1 T 1 = p 2 V 2 T 2.applies.The air pressure is the same as the pressure of the surrounding water,and the volume of the bubble can be determined by the volume formula of a sphere V = 4 3 r 3.Now we substitute these relations into the state equation.( p a + h g) 4 3 r 1 3 T 1 = p a 4 3 r 2 3 T 2.
