For a mixture of methanol (1) and methyl acetate (2): a.) Assume the mixture is found to obey Raoult’s law. At 60ºC and x1 = 0.25, what is the system pressure and the composition in the vapor? b.) Assume the mixture is found to obey Raoult’s law. At 60ºC and 90 kPa, what are the compositions in each phase? c.) Assume the mixture is NOT an ideal solution, and instead follows Modified Raoult’s law. It has been found experimentally that: ln(%) = 1.25x- - and ln(-) = 1.25x% -. At 100ºC and x1 = 0.75, what is the system pressure and the composition in the vapor?

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg

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.
