Question

A non-flow system undergoes a fric-
tionless process according to a law p = (4.5/v) + 2, where
p is in bar and the volume v is in mº/kg. During the pro-
cess, the volume changes from 0.12 m /kg to 0.04 m®/kg
and the temperature increases by 133°C. The change in
internal energy of the fluid is given as du = Cydy, where
Co = 0.71 kJ/kg . K and dT is temperature change. Find
out (a) heat transferred, and (b) change in enthalpy.
Assume a fluid quantity of 10 kg.​
