दो तापमानों के बीच संचालित होने वाले ऊष्मा इंजन की कार्नोट दक्षता है:
\( \eta = 1 - \frac{T_2}{T_1} \)
जहाँ, \( T_1 \) स्रोत तापमान है और \( T_2 \) सिंक तापमान (केल्विन में) है।
दिया गया है:
स्रोत तापमान = 900°C = 1173 K
सिंक तापमान = 35°C = 308 K
शुद्ध उत्पादन कार्य = 1 kW
परिणाम:
दक्षता, \( \eta = 1 - \frac{308}{1173} = 0.7375 \)
आपूर्ति की गई ऊष्मा, \( Q_1 = \frac{1}{0.7375} = 1.356 \, \text{kW} \)
अस्वीकृत ऊष्मा, \( Q_2 = Q_1 - W = 1.356 - 1 = 0.356 \, \text{kW} \)
