Consider a heat engine as shown in figure. `Q_(1)and Q_(2)` are heat added both to `T_(1)` and heat taken from `T_(2)` in one cycle of engine. W is the mechanical work done on the engine.

If `Wgt0`, then possibilities are

Consider a heat engine as shown in (figure). Q_(1) and Q_(2) are heat added to heat bath T_(1) and heat taken from T_(2) one cycle of engine. W is the mechanical work done on the engine. If Wgt0 , then possibillities are:

A heat engine absorbs heat Q_(1) at temperature T_(1) and Q_(2) at temperature T_(2) . Work done by the engine is (Q_(1)+Q_(1)) . This data:

A heat engine works between a source and a sink maintaned at constant temperatures T_(1) and T_(2) . For the efficiency to be greatest

A Carnot's engine woeking between 27^(@)C and 127^(@)C takes up 800 J of heat from the reservoir in one cycle. What is the work done by the engine

A reversible heat engine A (based on carnot cycle) absorbs heat from a reservoir at 1000 K and rejects heat to a reservoir at T_(2) . A second reversible engine B absorbs, the same amount of heat as rejected by the engine A, from the reservoir at T_(2) and rejects energy to a reservoir at 360 K. If the efficiencies of engines A and B are the same then the temperautre T_(2) 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.

The efficiency of carnot's heat engine is 0.5 when the temperature of the source is T_(1) and that of sink is T_(2) .The efficiency of another crot's heat engine is also 0.5.the temperature of source and sink of the second engine are respecitvely
