This question requires the use of the Thermodynamic Property Tables supplied as additional material. A closed system comprises a rigid (non-deformable) vessel of volume 0.3 m³ containing 5 kg of pure water substance, initially at a pressure of 30 bar (state 1). (a) For state 1, show that the system is in the two phase region. The system now undergoes an isochoric (constant volume) process during which its pressure increases to 70 bar (state 2). (b) For state 2 show that the system is now in the superheated region. (c) Sketch the process described above on a pressure v specific volume diagram. Include in your sketch the boundaries between the liquid, two phase and vapour regions, and the critical pressure. (d) If no work is done on or by the system during the process, evaluate the heat transfer TO the system.
