Agrit chamber is designed for a flow-through velocity of 0.30 m/s, a depth of 0.9 m, and a length of 10.5 m. if inorganic particles have a specific gravity of 2.65, estimate the diameter of the largest particle that can be removed 100% at 20 degrees c.

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.
