Example Problem

Given a first single stage of an Axial Compressor with the following conditions: ambient pressure (Pin) 1 atmosphere, ambient temperature (Tin) 300K, aircraft cruising speed (Vin) 170m/s, median blade diameter (D) 0.5m, rotor rpm (Urotor) 8000rpm, turning angle (Db) 15 degrees, specific heat ratio (g) 1.4, air mass flow rate (mdot) 35kg/s, and (Cp) conversion factor 1004 m2/s2*K, calculate the first stage Compressor Pressure Ratio (CPR).
