Engineering ratios

Overall pressure ratio

In aeronautical engineering, overall pressure ratio, or overall compression ratio, is the ratio of the stagnation pressure as measured at the front and rear of the compressor of a gas turbine engine. The terms compression ratio and pressure ratio are used interchangeably. Overall compression ratio also means the overall cycle pressure ratio which includes intake ram. (Wikipedia).
