An inventor claims to have devised a closed cyclic engine which exchanges heat with cold and hot reservoirs at 25 and 350 ◦C, re

kati45 [8]

Explanation:

The given data is as follows.

$T_{c} = 25^{o}C$ , $T_{h} = 350^{o}C$

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 $[1 - (\frac{T_{c}}{T_{h}} )]$

Using this relation we will calculate the efficiency as follows.

Efficiency = $[1 - (\frac{T_{c}}{T_{h}} )]$

= $1 - (\frac{25}{350})$

= 0.928

Hence, it means that this type of device is possible and the claim is also believable.
