The properties of a system.. at p = 1.6 bar.. solved problem



The properties of a system, during a reversible constant pressure non-flow process at p = 1.6 bar, changed from v1 = 0.8 m3/kg, T1 = 20°C to v2 = 0.55 m3/kg, T2 = 260°C. cp = ( 1.5 + 75/T + 45 ) kJ/kg °C , where T is in °C. Determine : (j) Heal added/kg ; (ii) Work done/kg ; (iii) Change in internal energy/kg ; (iv) Change in enthalpy/kg.
