Question

A Carnot engine takes an amount of heat QH = 113 J from a high-temperature reservoir at temperature TH = 1170°C, and exhausts the remaining heat into a low-temperature reservoir at TL = 13.3°C. Find the amount of work that is obtained from this process

Answer 1

First, convert temperatures to absolute units.
TH = 1443 K
TL = 286.5 K
Carnot Efficiency =
Wout/Qin = (Qin - Qout)/Qin
= 1 - (Tc/Th) = 0.802

Work out = (efficiency)*113 = 90.6 J
