Revisit Example 6 from your Module 4 notes. Consider the well-insulated, rigid tank having a volume of 10 [ft']. Previously, it contained saturated water vapor at 212°F at state 1. The water was rapidly stirred until the pressure was 20 [Ibfin'j. In class we showed that the temperature at state 2 was 445°F and the work done during this process was -31.3 [Btu]. Now, if insulation were removed from the tank, and the water is cooled at constant volume from T: = 445°F to T3= 300°F without stirring the water, determine: a) The pressure at the state 3 in (Ibfin), and b) The heat transfer during the process in [Btu].
