Explanation:
The given data is as follows.
,
Work produced per kJ of heat extracted from hot reservoir = 0.45 kJ = Efficiency
If the device is Carnot cycle then its efficiency will be maximum and its value will be equal to
Using this relation we will calculate the efficiency as follows.
Efficiency =
=
= 0.928
Hence, it means that this type of device is possible and the claim is also believable.
