Question

. At some section in the convergent-divergent nozzle, in which air is flow￾ing, pressure, velocity, temperature and cross-sectional area are 200 kN/m2, 170 m/s, 200

Answer 1

At some section in the convergent-divergent nozzle, in which air is flowing, pressure, velocity, temperature and cross-sectional area are 200 kN/m², 170 m/s, 200°C and 1000 mm? respectively. If the nozzle efficiency is 98%, determine C 1 1 Stagnation temperature and stagnation pressure, 1.2 sonic velocity and Mach number at this section, 2 1.3 Velocity. Mach number and flow area at outlet section where pressure is 110 kN/m² and 1.4 Pressure, temperature, velocity and flow area at throat of the nozzle. Take for air: R = 287 J/kg K, cp = 1.0 kJ/kg K and y = 1.4.
