Load the records of exercise 16.31 into expandable hash files based on extendible hashing. show the structure of the directory at each step, and the global and local depths. use the hash function h(k) = k mod 128.what are the optical and tape juleboxes?

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.
