• Atmospheric Pressure - 309 Words
Atmospheric pressure is the force per unit area exerted on a surface by the weight of air above that surface in the atmosphere of Earth (or that of another planet). In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the mass of air above the measurement point. Low-pressure areas have less atmospheric mass above their location, whereas high-pressure areas have more atmospheric mass above their location. Likewise, as elevation increases, there...

• Breaking a Ruler with Atmospheric Pressure
﻿ Breaking a Ruler with Atmospheric Pressure Introduction In this experiment, I will try to use air pressure, along with some sheets of newspaper, to attempt to break a ruler. Air pressure is the weight of the atmosphere pressing down on the earth. A device called a barometer measures it in units called millibars. Most barometers use mercury in a glass column, like a thermometer, to measure the change in air pressure. I came up with this idea from when I read in a book about how some kids...

Chapter 3 Pressure Measurement Examples Example 3.3 A special high pressure U tube manometer is constructed to measure pressure differential in air at 13.8 MPa and 20oC. When an oil having a specific gravity of 0.83 is used as the fluid, calculate the differential pressure in N/m2 that would be indicated by a 135 mm reading. p − pa = m g h( gc m − f ) = (0.83)(1000) = 830kg/m 3 = = p 13.8 × 10 6 = f a RT (287)(293) g h( m − f ) p − pa = gc = 9.81(0.135)(830 − 164.11) = 881.51N/m 2...

• Pressure - 634 Words
According to the essay “Too Much Pressure” by Colleen Wenke, the reason that students cheat on their tests is because they are under too much pressure to get good grades, which is accurately portrayed since cheating is usually seen as one of the only ways to pass tests and that’s what students are being stressed to do. Based on her essay, teachers should be teaching students right from wrong as opposed to pressuring to the extent of making them cheat. This is important to see because it is a...

• ‘Low pressure atmospheric systems have more of a short term impact than high pressure systems.’ Discuss.
‘Low pressure atmospheric systems have more of a short term impact than high pressure systems.’ Discuss. Low pressure atmospheric systems are also known as depressions or cyclones and they form in mid- and high-latitudes. They are formed by the mixing of cold and warm air, the warm air is lighter, so it rises above the denser, cold air and forms a centre of low pressure. High pressure atmospheric systems are also known as anticyclones and have very different characteristics to depressions....

• Air Pressure - 451 Words
Air Pressure Air is composed of molecules. Air is matter. It has mass and takes up space. Air is composed of different gases such as nitrogen, oxygen, carbon dioxide, water vapor, and other gases. Air molecules are in constant motion. As they move, they come in contact with surfaces. Air molecules push and press on the surfaces they contact. The amount of force per unit area that air molecules exert on a surface is called air pressure. (What is Air Pressure 6) Air pressure is caused by...

• pressure gauge - 380 Words
A pressure gauge is an instrument that measures the pressure in a vessel, a line, or whatever the pressure gauge is connected to. A Bourdon gauge consists of a C-shaped pipe with one end closed and the other end attached to a chamber whose pressure is being measured. When there is a pressure difference between the inside of the pipe and the outside, there will be a net force acting on the C-shaped pipe which will either try to curl the pipe into a tighter C shape (if the pressure in the pipe is...

• pneumatic controls - 28537 Words
INTRODUCTION 1 INTRODUCTION A fluid power system is one that transmits and controls energy through the use of pressurised liquid or gas. In Pneumatics, this power is air. This of course comes from the atmosphere and is reduced in volume by compression thus increasing its pressure. Compressed air is mainly used to do work by acting on a piston or vane. While this energy can be used in many facets of industry, the field of Industrial Pneumatics is considered here. The correct use of...
