Compressible Flow Tables and Plots

Engineering Software, profile picture
Engineering Software

This document contains data tables and plots related to nozzle and diffuser flow. It includes input parameters like stagnation temperature and pressure, output parameters like velocity and Mach number, and calculated values like temperature, pressure, and thrust. Tables of 61 rows show how the values change across steps of 10 m/s from 0 to 600 m/s for the nozzle, and 30 rows from 0 to 300 m/s for the diffuser. Accompanying plots graphically depict the relationships.
