Air flows from a reservoir maintained at 20 c and 200 kpa absolute through a converging -diverging nozzle that has 15 cm diameter throat. find the diameter where m=2.5 using equations only.

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.

What is the major difference between thermoplastics and thermosetting plastics from the polymerization structure point of view?
