The volume fraction of particles in a wc-particle cu-matrix cermet is 0.65 calculate the minimum expected elastic modulus, in gpa, of this particle reinforced composite. the moduli of the two components are 682 gpa and 110 gpa, respectively. use what you know about these composite phases to discern which modulus is which. answer format: x unit: gpa 127.

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.
