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

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
