Air flows through a nozzle which has inlet areas of
(10 cm2
). If the air has a velocity of (120 m/s) a
temperature (300K) and a pressure of (700kpa) at the inlet section
and a pressure of (250kpa) at the exit,
find the mass flow rate through the nozzle and the velocity at the
exit of the nozzle, assuming one-
dimensional isentropic flow. (R=287 J/kg. K), (K=1.4). (25%)
