In gas turbines–brayton cycle lecture, the brayton cycle example was solved assuming constant values for the specific heat cp within each of the processes. using the variable specific heat for air given in eq. (1-19), recalculate: (a) the ideal compressor work, (b) the ideal turbine work, and (c) the heat added to the cycle. for each of these three answers, what is the percentage error in the original estimate using a constant cp? you may use the temperatures t1, t2, t3 and t4 from the class example. (suggestion: look at your solution to problems 1-4 and 1-5.) [15 pts]
