A carnote engine absorbs `8 KJ` of energy at `400K`. If sink is maintained at `300 K`, Calculate useful work done per cyclic (in joule) by the engine.

During isothermal expansion at 800 K, the working substance of a Carnot's engine extracts 480 cal of heat. If the sink be at 300 K, calculate (i) the work done by the working substance during isothermal expansion (ii) the work done on the substance during isothermal compression (iii) the efficiency of the ideal engine.

A Carnot engine absorbs 300 cal of heat from a reservoir and rejects 250 cal of heat at 300 K during each cycle. Calculate: The efficiency of engine.

A carnot engine operates between 500 K and 400 K. If it absorbs 6 xx 10^(5) cal. heat at higher temperature, how much work per cycle can the engine perform ?

A Carnot engine works between 600K and 300K. The efficiency of the engine is

A Carnot engine works between 600K and 300K. The efficiency of the engine is

A carnot engine takes in 1000 K cal of heat from a reservoir at 627^(@)C and exhausts heat to sink at 27^(@)C . What is its efficiency? What is useful work done//cycle by the engine.

A carnot engine absorbs heat from a reservoir maintained at temperature 1000K. The engine rejects heat to a reservoir whose temperature is T. If the magnitude of a absorbed heat is 400J and work performed is 300J, then the value of T is

A carnot engine operates between two reservoirs of temperature 900K and 300K. The engine performs 1200 J of work per cycle. The heat energy delivered by the engine to the low temperature reservoir in a cycle is:
