Question

10 kg of saturated liquid ammonia at 10c. 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/kg.K, the entropy (in kj/kg.K) of saturated vapour is

Answer 1

closed system contains 10 kg of saturated liquid ammonia at 100C. 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/kg.K, the entropy (in kJ/kg.K) of saturated v

Answer 2

Explanation:

for closed system , ∆Q= TDS

∆Q= mT(Sg-Sf)

Sg=∆Q/mT +Sf

put value we get =6.604 KJ/kgk
