During Atterberg limit tests in the soil mechanics laboratory, the students obtained the following results from a clayey soil. Liquid limit tests: Number of blows, N Moisture content (%) 14 38.4 16 36.5 20 33.1 28 27.0 Plastic limit tests: Students conducted two trials and found that PL 5 17.2% for the first trial and PL 5 17.8% for the second trial. (a) Draw the flow curve and obtain the liquid limit. (b) What is the plasticity index of the soil? Use an average value of PL from the two plastic limit trails.

Air (c-1.006 kj/kg. k, r-0.287 kj/kg. k) enters a nozzle steadily at 280 kpa and 77°c with a velocity of 50 m/s and exits at 85 kpa and 320 m/s. the heat losses from the nozzle to the surrounding medium at 20°c are estimated to be 3.2 kj/kg. determine (a) the exit temperature and (b) the total entropy change for this process. solve this problem using constant specific heats.
