Problem 2 - [3 points] Consider air flowing through an adjustable C-D nozzle. The atmospheric pressure is
p_(a)=0.1bar. The throat area
A_(t)=0.125m^(2)and the exit area is
A_(e)=0.5m^(2). The reservoir temperature is 1000 K. (a) Determine the reservoir pressure, nozzle exit pressure, and nozzle exit Mach number when a shock occurs within the diverging section of the nozzle at
(A)/(A_(t))=2.0. (b) Determine the mass flow rate and thrust. (c) Reclassify the nozzle flow if the nozzle exit area is reduced to
0.250m^(2). Use the same reservoir pressure computed from part (a). Also, determine nozzle exit pressure and Mach number. HINT: Verify that exit mach number is 0.468 (d) Determine the mass flow rate and thrust for the scenario described in part (c).
