Using the given slab thickness of 6 in., determine the required reinforcement size and spacing at both of these locations to satisfy ACI Code flexural strength requirements. Be sure to check the ACI Code requirements for minimum flexural reinforcement in slabs.

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.
