1.5 kg of water is in saturated liquid state at 2 bar (vf = 0.001061 m3/kg, uf=504.0kJ/kg, hf = 505 kJ/kg). Heat is added in a constant pressure process till the temperature of water reaches 4000C (v-1.5493m3/kg, u =2967.0 kJ/kg, h = 3277.0 kJ/kg). The heat added (in kJ) in the process is _________
