Air flows through a device such that the stagnation pressure is 0.4 MPa, the stagnation temperature is 400°C, and the velocity is 520 m/s. Determine the static pressure and temperature of the air at this state
4)Carbon dioxide flows steadily through a varying cross-sectional-area duct such as a nozzle shown in
the figure. The throat area is (10+0.1*A) cm². The carbon dioxide enters the duct at a pressure of
(1400+A) kPa and 200°C with a low velocity, and it expands in the nozzle to a pressure of 200 kPa. The
duct is designed so that the flow can be approximated as isentropic. Determine the flow rate in the
nozzle. A = LAST DIGIT OF YOUR CLASS ID
