Problem-Solving Strategies

Question 1

How should you approach mixed-phase property problems?

Answer 1

1. Determine the phase using T_sat or P_sat
2. Use quality (x) for mixed-phase:

h = h_f + xh_fg

Question 2

How do you handle interpolation in property tables?

Answer 2

Use linear interpolation:

y = y1 + (y2-y1)[(x-x1)/(x2-x1)]

Where
x : Known value
y : Desired property
