Speed and density data were obtained by time-lapse photography on a highway. a linear regression analysis is applied to estimate parameters in greenshields’ model of traffic flow. a linear regression model takes the form us = a + bk, where us is space mean speed and k is density. linear regression analysis yields values of the coefficients a = 62.8 and b = – 0.57. determine the jam density (in veh/mi).

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
