Acivil engineer has decided that a parameter termed the "resilient modulus" is central in determining if asphalt roads develop ruts. measurements were made of the resilient modulus on a set of rutted and non-rutted roads. the results from these tests are given below. the units of these measurements are 10^6 kpa and were made at the same temperature(40 degree). using this data perform a hypothesis test to determine if the resilient modulus might be a good parameter to determine road rutting. rutted: 1.48, 1.88, 1.90, 1.23, 1.00 non-rutted: 3.06, 2.58, 1.70, 2.44, 2.03, 1.76, 2.86, 1.04, 2.82.

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.
