A Brayton cycle with regeneration and reheat generates 10 MW of power. Air enters the compressor at 100 kPa and 300 K. The compressor operates with a pressure ratio of 12 and an isentropic efficiency of 80%. The air enters the high pressure turbine stage at 1400 K and exits at a pressure of 350 kPa. The air is reheated to 1400 K before entering the second turbine stage. Each turbine stage has an efficiency of 80%. The regenerator has an effectiveness of 80%. Using an air-standard analysis, determine:

a. The pressure and temperature at each state, in kPa and K,

b. The mass flow rate of air, in kg/s,

c. The heat addition rate in kW,

d. The thermal efficiency of the cycle, and

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.
