6.107:

W-dot/m-dot = 532.6 kJ/kg Sgen-dot/m-dot = 0.5087 kJ/kgK (if To = 400 K) Sgen-dot/m-dot = 0.5337 kJ/kgK (if To = 300 K)

Hints:

• Read EACH word.
• Draw some pictures (one for each state).
• Write your assumptions
• Write the given information under each picture.
• Write what it is you are to find.
• If necessary, find the phase at each state. (you may need this to find the T-D properties)
• Write write the equations you are to use (or might want to use).
• Solve the problem...
• PLEASE try to be organized.
