Question
(II) A heat engine exhausts its heat at $340^{\circ} \mathrm{C}$ and has aCarnot efficiency of 38$\% .$ What exhaust temperature wouldenable it to achieve a Carnot efficiency of 45$\% ?$
Step 1
Step 1: The Carnot efficiency is given by the formula: \[ \eta = 1 - \frac{T_L}{T_H} \] where \(T_L\) is the lower operating temperature and \(T_H\) is the higher operating temperature. Show more…
