A sealed rigid vessel has a volume of 1 m³ and contains initially 2.12 kg of water at 100°C. The vessel is then heated till a maximum pressure of 400 kPa is reached.
Determine the following:
(70 pts.)
(a) Specific volume of water at the initial condition, $v_1$ in m³/kg.
(b) The phase of water at the initial state.
(c) If the initial phase is a saturation mixture, what is the quality, $x_1$.
(d) Internal energy at the initial state, $u_1$ in kJ/kg.
(e) Specific volume at the final state, $v_2$ in m³/kg.
(f) Final temperature, $T_2$.
(g) Internal energy at the final state, $u_2$ in kJ/kg.
(h) The work done during the process, $W_{1-2}$ in kJ/kg.
(i) The heat transfer during the process, $Q_{1-2}$ in kJ/kg.
show the states and the process in a P-v or T-v diagram
