Homework Answers
Solution:
Efficiency (
)
of steam engine is calculated as,
= (T2 - T1) / T2
Given, T1 = 15 °C + 273 = 288 K
T2 = 150 °C + 273 = 423 K
Thus,
= 423 - 288 / 423 = 135 / 423
Efficiency ()
of steam engine is also related with heat absorbed (Q) and work (W)
as,
= W / Q
W = Q x
= 5500 J x (135/423) = 1755.32 J
W = 1755.32 J

8. A refrigerator may be regarded as the inverse of a steam engine, in that work is performed in order to remove heat from a system. It may be regarded as a steam engine run in reverse (i.e. the first step is a reversible adiabatic expansion from Th to Tc.) Heat is removed from the gas at the lower temperature in the succeeding isothermal expansion. The efficiency of a refrigerator is: Er = Aqoutput/AWinput Assuming a refrigerator can be built...
