Assignment Help Mechanical Engineering
Reference no: EM13718180

Nitrogen gas (N2) undergoes a process from p1 = 10 bar, T1 = 300 K to p2 = 12 bar, T2 = 1000 K. Assuming ideal gas behaviour, determine the change in specific entropy, in kJ/(kg K), assuming:

a) Constant specific heats, evaluated from Table A-20 at 650 K

b) Using data from Table A-23 to evaluate the reference entropy
