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 heat rejected to the sink 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

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

A reversible engine converts one third input into work. When the temperature of the sink is reduced by 62 °C, then efficiency of the engine is tripled. The temperature of the source and sink are

Efficiency of a Carnot engine is 50% when temperature of outlet is 500 K . In order to increase efficiency up to 60% keeping temperature of intake the same what is temperature of outlet?

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 ?

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

The efficiency of a Carnot cycle is 1/6 . If on reducing the temperature of the sink by 65^@C , the efficiency becomes 1/3 , find the initial and final temperatures between which the cycle is working.

The difference in temperature between two sides of a glass plate 0.3 mm thick is 25^@C . If the area of one side surface is 10 m^2 , calculate the heat conducted per second through the plate. The thermal conductivity of glass is 0.84 J//s m K.
