In a heat engine , the temperature of the source and sink are 500 K and 375 K . If the engine consumes 25 xx 10^5 J per cycle, find work done per cycle

In a heat engine , the temperature of the source and sink are 500 K and 375 K . If the engine consumes 25 xx 10^5 J per cycle, find the efficiency of the engine.

If the absolute temperatures of the source and sink of a heat engine are in the ratio 4 : 3 , its efficiency is

When the absolute temperature of the source of a Carnot heat engine is increased by 25 %, its efficiency increases by 80%. The new efficiency of the engine is

A Carnot's engine used first an ideal monoatomic gas then an ideal diatomic gas. If the source and sink temperature are 411^@C and 69^@C respectively and the engine extracts 1000J of heat in each cycle, then area enclosed by the PV diagram is

Two Carnot engines A and B are operated in succession. The first one , A receives heat from a source at T_1 = 800 K and rejects to sink at T_2K . The second engine B receives heat rejected by the first engine and rejects to another sink at T_3 = 300K . If the work outputs of two engines are equal , them the value of T_2 is

743 J of heat energy is needed to raise the temperature of 5 moles of an ideal gas by 2 K at constant pressure. How much heat energy is needed to raise the temperature of the same mass of the gas by 2 K at constant volume ?

A Carnot engine, whose efficiency is 40% , takes in heat from a source maintained at a temperature of 500K. It is desired to have an engine of efficiency 60% . Then, the intake temperature for the same exhaust (sink) temperature must be:

Consider a Carnot 's cycle operating between T_1 = 500 K and T_2 = 300 K producing 1 kJ of mechanical work per cycle. Find the heat transferred to the enginer by the reservoirs.

Two engines A and B have their sources at 400 K and 350 K and sinks at 350 K and 300 K respectively. Which is more efficient and by how much ?
