What Does P3 Stand For?

P3 stands for Compressor Discharge Total Pressure

P3, or Compressor Discharge Total Pressure, refers to the total pressure measured at the discharge of a compressor. It represents the sum of the static pressure and dynamic pressure of the gas after compression, reflecting the compressor's performance and efficiency. P3 is a critical parameter in engine performance analysis, as it influences fuel efficiency, power output, and overall operational efficiency in various applications, including aviation and industrial processes. Accurate measurement of P3 is essential for effective system design and optimization.
