Answer #1

Dear student,

Inorder to calculate the outlet temperature condition, ee need to find entropy at inlet s2,

And by equating s1 =s2 we can obtain outlet condition , if this =s2 value is greater that S saturated value at 100 kpac, then look at superheated properties else it is either saturated or wet.

Note:

All the properties are taken at steam tables.

Numerical solved below,

Soin ol-08-2020 o Given Pi= 6Mpa T=400°C P2= 100kpa Tz=? from steapn tables; @ bapa and 400°C (Super heated steam properties
