Is Vacuum A Negative Pressure at Zane Denise blog

Is Vacuum A Negative Pressure. The pressure regimes listed above. Vacuum pressure (figure 2 labeled c) is a measure of the pressure of a gas in a space where the pressure is lower than atmospheric pressure. Low pressure is equivalent to a high vacuum. Any negative pressure significantly below standard atmospheric pressure (760 torr/mmhg, 29.9 inhg or 14.7 psi) is considered a vacuum. This gauge is calibrated at atmospheric pressure and reads only negative pressure or vacuum. There can be no such thing as negative pressure; In a vacuum, there is no atmospheric pressure, and hence, there is a negative pressure or absence of pressure. It is expressed as a negative. No, absolute pressure is measured with reference to a perfect vacuum so it is impossible for it to go negative. You can only measure negative pressure between two different pressures. Some engineers may not refer to vacuum at all but instead speak of “low pressure” or even “negative pressure”. Is it possible to have a negative absolute pressure? It is always a positive pressure but lower than atmospheric pressure. A gauge measuring negative pressure, that is, pressure lower than atmospheric or barometric pressure is called a vacuum pressure gauge.
