Question: Carbon dioxide (k = 1.28) enters a constant-area duct at 400F, 100 lbf/in2 absolute, and 500 ft/s. Farther downstream the properties are V2 = 1000

Carbon dioxide (k = 1.28) enters a constant-area duct at 400°F, 100 lbf/in2 absolute, and 500 ft/s. Farther downstream the properties are V2 = 1000 ft/s and T2 = 900°F. Compute
(a) P2, (b) the heat added between sections,
(c) The entropy change between sections, and
(d) The mass flow per unit area. Hint: This problem requires the continuity equation.
