| 1. | It consists of two terms which are absolute pressure and gravity head.
|
| 2. | However, the boiling point of water depends on the absolute pressure inside the pipe.
|
| 3. | For example, the absolute pressure compared to vacuum is:
|
| 4. | Torr and micron usually indicates an absolute pressure, while inHg usually indicates a gauge pressure.
|
| 5. | The absolute pressure in the tire is essentially unchanged.
|
| 6. | The air density is calculated using the absolute pressure and temperature in the intake manifold.
|
| 7. | The situation changes when extreme vacuum pressures are measured; absolute pressures are typically used instead.
|
| 8. | When the absolute pressure of the vacuum is decreased further, the flow speed will not increase.
|
| 9. | To produce an absolute pressure sensor the manufacturer will seal a high vacuum behind the sensing diaphragm.
|
| 10. | The pressure shown on a gauge would be the absolute pressure less atmospheric pressure, or 187.1 psi .)
