A Carnot power cycle taking place in a piston-cylinder device uses air as the working fluid, according to the T-s diagram below. Assuming the ideal gas model with Cp 1.005 kJ/kg-K determine: a. b. The pressure at states 1 and 2 in kPa. Heat and work transfer for process 1-2. No need to interpolate. Round the number to the closest value. If exactly between two values, use the larger one. Hint: Start with the equation for the entropy change for the process 2-3. For part b, remember that AS = Q/T. T 4 P-500 kPa 1400 K → AIR 350 K 3, p₁=100 kPa A Carnot power cycle taking place in a piston-cylinder device uses air as the working fluid, according to the T-s diagram below.
