Hi, Think I got it. Can you please double check my answers. I got the dryness fraction 95.01% and the change in enthalpy as 254.42 KJ/Kg Can you please check if I did this right ? Q) Steam enters the superheater of a boiler at 2000 kPa and 0.98 dry and leaves at the same pressure and a...

This is where I got stuck. I checked the steam tables for h value of superheated steam at 2000 kpa and 250 degree centigrade. Got the values of hf and hfg of wet saturated steam at 2000 kpa, used the formula x= hsup-hf/hfg and got a value more than 1. This cannot be right because the dryness...

Need some help here please, Steam at 2000 Kpa and 250 degree centigrade is expanded isentropically to a pressure of 550 Kpa. Determine the a) dryness fraction of steam b) change in specific enthalpy of steam

Do you mean from steam tables

dryness fraction - is anything missing here ?? Hi Guys, Got a couple of questions I need answers on. a)A closed vessel of 0.8 m3 capacity contains dry saturated steam at 350 kPa. The vessel is cooled until the pressure is 200 kPa. Calculate 1) mass of steam in the vessel 2) final dryness...
