Here are four types of pressure: 1. Absolute Pressure: This is the pressure measured relative to a perfect vacuum (zero pressure). It includes the atmospheric pressure. For example, a tire pressure gauge reading of 30 psi (gauge) would be approximately 44.7 psi (absolute) at sea level. 2. Gauge Pressure: This is the pressure measured relative to the ambient atmospheric pressure. Most pressure gauges, like those for car tires or air compressors, display gauge pressure. A positive gauge pressure indicates pressure above atmospheric, while a negative gauge pressure (vacuum) indicates pressure below atmospheric. 3. Atmospheric Pressure: This is the pressure exerted by the weight of the air in the Earth's atmosphere. It varies with altitude and weather conditions. At sea level, standard atmospheric pressure is approximately 101.325 kPa or 14.7 psi. 4. Differential Pressure: This is the difference between two pressures. It is often used to measure flow rates, liquid levels, or filter conditions in industrial applications. For instance, a differential pressure sensor might measure the pressure drop across an orifice plate to determine fluid velocity. 3 done, 2 left today. You're making progress.
