Q3:Figure 1 shows the modified Brayton cycle. Based on the figure and assuming constant specific heats parameters, гp=pc=A and the working fluid is air, answer the following: Compressor Turbine Turbine 1 3 6 S 1- Plot the P-V diagram. 2- Identify each of the processes given on the figure and what kind of improvement is made to this gas cycle. 2- Assuming T1=25C and T3-T5= 665C and based on estimating the various works done per unit mass, calculate the thermal efficiency of this cycle k=1.4). (Consider the heat constants at room temperature,
