Question
![An ideal gas in a piston-cylinder assembly undergoes a
totally reversible Carnot cycle.
The isothermal compression occurs at 330 K from 100
kPa to 140 kPa while discharging 880 kJ of heat. The
thermal efficiency is 45%.
a)
What is the temperature of the isothermal
expansion, in K?
b)
What is the amount of heat transferred in during the
isothermal expansion, in kJ?
1In a real power cycle, would you expect the actual
thermal efficiency to be above, below, or the same as
stated in the problem?
d) [ ]A technician measures performance data and
reports that while the temperatures match the model, the
actual heat discharge is 870 kJ and the actual heat
received is 1900 kJ. Is this possible?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1606b766-bfa8-4083-9557-a4bb20db7c66%2Fd012348f-9e83-4fe1-b177-27baba01df03%2F3dklaj_processed.jpeg&w=3840&q=75)
