Why does the pressure in a compressor have a unit PSI instead pound? If the pressure of a compressor is 10 PSI, would a 10 sq in nozzle cause the pressure to drop to 1 psi?

Psi stands for "pounds per square inch," and it is a unit of pressure commonly used in scientific and engineering applications. It is used to measure the amount of force exerted on a surface per unit area, which is an important consideration in many fields. Pounds, on the other hand, are a unit of weight and do not take into account the area over which the force is distributed. Therefore, psi is a more accurate and precise unit for measuring pressure.
Yes, psi is a standard unit of measurement in the International System of Units (SI) and is commonly used in the United States. It is also recognized by the International Organization for Standardization (ISO) and the American National Standards Institute (ANSI).
Psi is commonly used in industries such as automotive, aerospace, and construction to measure tire pressure, engine compression, hydraulic systems, and building materials' strength. It is also used in meteorology to measure atmospheric pressure and in medical devices to measure blood pressure.
Psi can be converted to pounds by multiplying the psi value by the area over which the force is applied. For example, if a force of 100 pounds is exerted over an area of 10 square inches, the psi would be 10 psi (100 pounds / 10 square inches). Conversely, to convert pounds to psi, you would divide the pounds by the area.
Psi is a more practical unit for measuring pressure because it takes into account the surface area over which the force is applied. This is important because the same amount of force can have a different impact depending on the area it is distributed over. For example, a small nail and a large hammer may both have the same amount of force, but the nail will exert more pressure on a surface due to its smaller area. Psi allows for more accurate and precise measurements in various applications.
