The properties of a system, during a reversible constant pressure non-
flow process at P=1.6 bar, changes from V,=0.3m'/kg, t;=20°C to
V=0.55m²/kg, tz=260°C. The specific heat of the fluid is given by
Cp=1.5+75/(t+45) kJ/kg°C where t is in °C.
Determine:
i. Heat added/kg
ii. Change in internal energy/kg
iii. Change in enthalpy/kg
