Question
A piston cylinder assembly contains steam.
Initially, the specific internal energy (internal
energy per unit mass) is equal to 2800
kJ/kg. The steam undergoes a process
during which 90 kJ of heat is transferred to
the steam. On the other hand, using a
specific mechanism installed in the cylinder,
20 kJ of energy are transferred to the steam
by work. If 10 kJ of heat is dissipated from
the steam to the outside of the cylinder
through the wall of the cylinder, Determine
the work done by the steam on the piston.
The specific internal energy at the final state
is equal to 2500 kJ/kg. The mass of the
steam is 7.7 kg.
Select one:
a. 1893 kJ
b. 2410 kJ
c. 1450 kJ
d. 1650 kJ
