A closed system contains 10kg of saturated liquid ammonia at 10°C. Heat addition required to convert the entire liquid into saturated vapour at a constant pressure is 16.2 MJ. If the entropy of the saturated liquid is 0.88 kJ/kgK, the entropy (in kJ/kgK) of saturated vapour is____
-
- 6.6013 kJ/kg
- 5.6013 kJ/kg
- 7.6013 kJ/kg
- 8.6013 kJ/kg
Correct Option: A
Tds = du + pdv (closed system)
283.15 × 10(S2 – S1) = 16.2 × 103
| ∴ S2 = 0.88 + | 283.15 × 10 |
= 6.6013 kJ/kg
