An ideal rankine cycle with reheat uses water as the working fluid. the conditions at the inlet to the high-pressure turbine are 10mpa, 650°c and the steam is reheated at a constant pressure o f 1.4mpa before entering the low-pressure turbine. for a condenser pressure of 10kpa, plot the cycle thermal efficiency and quality of steam at the low- exit versus reheat temperatures (the temp of steam entering the low pressure turbine) of 300, 400, 500, and 600°c (15 points). draw the t-s diagram and show all your work for a reheat temperature of 300°c. note: : there will be two plots. one with thermal efficiency on in the ordinate versus reheat temperate and the other will have quality on the ordinate versus reheat temperature .be sure to label all axes with variables and units and include title. the plots must be done on computer,

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.
