2 10 points Using the Ts diagram A9 please evaluate the spec

2. (10 points) Using the T-s diagram A-9, please evaluate the specific entropy of H2O at p = 4bar and h = 1600kJ / kg (5p). Please also check the result with the help of the property tables (5p)

Solution

FROM THE GRAPH ,

P=4bar

h=1600KJ/Kg

corresponding S=4.5KJ/Kg k

from steam tables,

sfg=5.1167 KJ/KGK
