5020 Joules.The maximum theoretical performance of an warmth engine ise = 1 - Tc/Thwheree = efficiencyTc = cold temperature (absolute)Th = warm temperature (absolute)So let"s transform the temperatures from C to K.Tc = 20 + 273.15 = 293.15 KTh = 600 + 273.15 = 873.15 KAnd instead of the values into the formula.e = 1 - 293.15/873.15e = 1 - 0.335738418e = 0.664261582Since our engine is only operating at 30% that this efficiency, the actual effectiveness is0.3 * 0.664261582 = 0.199278474So in order to carry out 1000 J the work, 1000 J / 0.199278474 = 5018.103448 J of power must be extract from the hot reservoir. Rounding to 3 far-reaching figures provides 5020 Joules.

The power required by the engine from the reservoir to execute

*
of work-related is
*
.

Further Explanation:

Given:

The temperature the the an initial reservoir is

*
or
*
.

The temperature the the second reservoir is

*
or
*
.

Concept:

The maximum feasible efficiency of a warmth engine working between the energy reservoirs at different temperatures is:

*

Here,

*
is the effectiveness of the engine,
*
is the temperature of the first reservoir and
*
is the temperature that the second reservoir.

Substitute the values of

*
and also
*
in over expression.

*

Now the efficiency of the engine is

*
the its maximum possible efficiency.

*

The effectiveness of the engine is characterized as the proportion of the job-related done come the quantity of power extracted by the engine.

*

Substitute the values of

*
and
*
in over expression.

*

Thus, the energy required by the engine from the reservoir to execute

*
of occupational is
*
.
