Determining the Phase State of a Pure Substance
Portions of a pressure table and a temperature table, both for saturated ammonia, are shown below. For each of the six states listed below the tables, determine whether ammonia is subcooled liquid, superheated vapor, saturated liquid, saturated vapor or two phase. Then click on "answer" to check your result.
Saturated Ammonia - Pressure Table
| P(bars) 12 14 16 |
T(oC) 30.94 36.26 41.03 |
vf x 10-3 (m3/kg) 1.684 1.708 1.731 |
vg (m3/kg) 0.1075 0.0923 0.0808 |
Saturated Ammonia - Temperature Table
| P(bars) 12.38 13.90 15.55 |
T(oC) 32 36 40 |
vf x 10-3 (m3/kg) 1.689 1.707 1.726 |
vg (m3/kg) 0.1043 0.0930 0.0831 |
