     3.5 kg of water in a two-phase liquid-vapor mixture with a quality 0.5 is at 340 C is in a rigid tank. The mixture is stirred adiabatically with a paddle wheel until the water is a saturated vapor. Take the dead state to be 300 K and 1 bar.  Determine:  the change in energy of the water;  the net amount of energy transfer by work and hear; and  c. the amount of energy destruction. 
  
  Solution
The change in exergy of water is 1.46
The netamount of energy transfer is you kj
The net exergy destruction is 5.6
