Air contained in a rigid, insulated tank fitted with a paddle wheel, initially at 4 bar, 40oC and a volume of 0.2 m3, is stirred until its temperature is 353oC. Assuming the ideal gas model with γ=1.4 for the air. Ignore kinetic and potential energy. Determine: (a) (10%) the final pressure, in bar; (b) (15%) the work, in kJ; (c) (15%) the amount of entropy produced, in kJ/K.

Abrayton cycle operates with a regenerator on the air-standard with properties evaluated at 400 k. the tem- perature of the air entering the compressor is 350k while the temperature of the air exiting the compressor is 600 k. the temperature of the air entering the turbine is 1600 k. the overall cycle produced 600 kj/kg of net work out. assuming a regenerator effectiveness of 0.8, what is the temperature of the air before heat addition (combustion)? draw this process on a t - s diagram
