Hello, I need help with this problem of thermodynamics 4?
from pj = 35 bar to p2 = 7 bar. The pressure-volume relationship during the process is pV2 = cte. The mass of steam is
to 2.3 kg. Other properties of the vapor in the initial state are: u, = 3.282,1 kj / kgy v1 = 113.24 cm3 / g. In the state
final u2 = 2,124.6 kj / kg. Neglecting changes in energy
kinetics and potential, calculate the heat transfer, in
kj, for steam considered as a system
