Problems:
3.56
3.93, using equation in table A-21
4.10
4.13
4.14
4.15b,c

Answers:
3.56: ₁W₂/m = 221.2 kJ/kg; ₁Q₂/m = 249.5 kJ/kg
3.93: delta-h = 1489.3 kJ/kg; delta-u = 1240.5 kJ/kg (from solution manual)
4.10: (a) m-dot = 0.348 kg/s, (b) A₂ = 1.74 cm²
4.13: (a) vel₁ = 3.74 m/s; (b) d₂ = 0.60 cm
4.14: d₂ = 0.915 m; d₃ = 3.35 m
4.15b,c: No answers will be given

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 "u"s, "v"s)
• Write write the equations you are to use (or might want to use).
• Solve the problem...
• PLEASE try to be organized.
