1. A meteorite melts and burns up at a temperature of 3000 K. If it hits air at 5 kPa, 50 K, how high a velocity should it have to experience such a temperature?
2. Air leaves a compressor in a pipe with a stagnation temperature and pressure of 150?C, 300 kPa, and a velocity of 125 m/s. The pipe has a cross-sectional area of 0.02 m2. Determine the static temperature and pressure and the mass flow rate.
