Question

In a steam power cycle, the steam supply is at 15 bar and dry and saturated.
The condenser pressure is 0.4 bar. Calculate the Carnot and Rankine efficiencies of the
cycle. Neglect pump work.

Answer 1

Answer:

Explanation:

efficiencies of the cycle. Neglect pump work.Take properties of steam at 15 bar,T1=198.3°C, h1 = 2789 KJ/Kg, S1 = 6.4406 KJ/KgK. At 0.26 bar,T2=75.9°C,

hf=317.7 KJ/kg, hfg = 2319.2 KJ/kg, vf=0.001017 m3/kg, sf =1.0261KJ/kgk and sfg = 6.6448 KJ/KgK
