Air at 600 kpa and 500 k enters an adiabatic nozzle that has an inlet-to-exit area ratio of 3: 1 with a velocity of 120 m/s and leaves with a velocity of 380 m/s. determine (a) the exit temperature and (b) the exit pressure of the air.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
