1) a) Sketch an open Joule (gas turbine) cycle on a T-s diagram when compression and expansion are: i) ideal; [6 marks] [4 marks] ii) non-ideal. b) An ideal open Joule cycle has compression and expansion pressure ratios that are both equal to rp 15.0. The pressure and temperature at the compressor inlet are P01 = 1.0 bar and To1 = 300K. The turbine inlet temperature is T03 = 1760 K. Assume cp = 1.0 kJ/kg K, the ratio of specific heats, y = 1.4, and very low velocities throughout the cycle. Calculate: i) The temperatures at the end of compression, To2, and end of expansion, T04, the work done in the compressor and turbine; and the heat addition in the burner; [10 marks] [5 marks] ii) the thermal efficiency of the cycle. 1) a) Sketch an open Joule (gas turbine) cycle on a T-s diagram when compression and expansion are: i) ideal; [6 marks] [4 marks] ii) non-ideal. b) An ideal open Joule cycle has compression and expansion pressure ratios that are both equal to rp 15.0.
