1/100 L. A heat engine operates between two temperature limits of 1300 K and 400 K. It receives 1.2 MJ of heat while producing 500 kJ of useful work. Determine: a. The exergy of the heat received by the heat engine. b. The energy that is not available for work production. c. The irreversibility of the process.

Step 1
The energy that is not available for work production can be determined using the efficiency of the heat engine. The efficiency of a heat engine is given by the formula: Efficiency = (Useful work output) / (Heat input) In this case, the useful work output is Show more…

Calculate An ideal heat engine operates between the temperatures $390 \mathrm{~K}$ and $240 \mathrm{~K}$. (a) How much heat must be given to the engine to produce $1200 \mathrm{~J}$ of work? (b) How much heat is discarded to the cold reservoir as this work is done?
Carnot engine working between $300 \mathrm{~K}$ and $600 \mathrm{~K}$ has work output of $800 \mathrm{~J}$ per cycle. What is amount of heat energy supplied to the engine from source per cycle (A) $1600\{\mathrm{~J} /$ (cycle)\} (B) $2000\{\mathrm{~J} /(\mathrm{cycle})\}$ (C) $1000\{\mathrm{~J} /($ cycle $)\}$ (D) $1800\{\mathrm{~J} /($ cycle $)\}$
Two Carnot engines $\mathrm{l}$ and 2 conneted in series deliver equal work. If 1 receives energy at $900 \mathrm{~K}$ and $B$ rejects energy at $400 \mathrm{~K}$. The temperatue for rejection in 1 is (a) $650 \mathrm{~K}$ (b) $700 \mathrm{~K}$ (c) $800 \mathrm{~K}$ (d) $500 \mathrm{~K}$
