The efficiency of a particular car engine is 26 percent when the engine does 7.0 kJ of work per cycle. Suppose the process is reversible.
(a) Find what is the energy the engine gains per cycle as heat Qgain from the fuel combustion?
kJ
(b) Obtain the energy the engine loses per cycle as heat Qlost?
(c) If a tune-up increases the efficiency to 32 percent, find what is Qgain at the same work value?
(d) If a tune-up increases the efficiency to 32 percent, find what is Qlost at the same work value?
