Rate of V˙ 1 = 50 m3/s at p1 = 95 kPa, T1 = 285 K. The overall pressure ratio p2/p1 = 24, and the turbine inlet temperature is T3 = 1950 K. The isentropic efficiencies of the compressor and turbine are ηc = 88% and ηt = 94%, respectively. Using cold air-standard Brayton cycle analysis, treating the gas as air modeled as a perfect gas with γ = 1.36, determine: (a) the net power developed in MW. (b) the rate of heat addition in the combustor, Q˙ in, in MW. (c) the thermal efficiency of the cycle η.

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.
