Question: 2 consider a brayton cycle composed of an isentropic compression...

Question details

2. Consider a Brayton cycle composed of an isentropic compression from 1 atm and 300k to 10 atm, a constant pressure combustion process with thermal energy added to bring the temperature at the end of that process to 1600K, followed by an isentropic compression process back to 1 atm. The working fluid is returned to its original state by a constant pressure thermal energy rejection process. The working fluid has the properties of air and expands to 0.1 atm. 1000 kJ (10 J) of thenal energy per kilogram of working fluid is added during the thermal energy addition portion of the cycle. a. Develop an expression for the temperature as a function of entropy for a constant pressure process b. Draw the Brayton cycle on the T-S diagram provided below c. Calculate the thermodynamic state of the gas (p, p, v, T at the beginning of each process which makes up the cycle. (assume a value for entropy at this location as the reference value). Calculate the entropy change per unit mass during the thermal energy addition portion of the cyele. Calculate the entropy change per unit mass during the thermal energy rejection portion of the cycle Calculate the total entropy change per unit mass for the cycle. Calculate the efficiency for the cycle Calculate the work per unit mass for the cycle. How much thermal energy is rejected? Hint, use the answer to parts f. d. e. f. h. i. Entropy (S)
