Q2: A spherical vessel of 0.9 m' capacity contains steam at 8 bar and 0.9 dryness fraction as shown in Figure 1. The steam is blown off through a valve until the pressure drops to 4 bar. The valve is then closed, and the steam is allowed to cool until the pressure falls to 3bor. Assuming that the enthalpy of the steam in the vessel remains constant during blowing off periods, determine: (1) The mass of the steam blown off (2) The condition of the steam in the vessel after cooling (find the dryness fraction or the degree of superheated depending on the condition)
