Got it, thanks so much Mike.  Is there a quantitave method to calculate it or is the chart look up the only method?

@MikeGlass1969 Which chart are you referring to? That value seems to be outside the bounds of the tables(both superheated and saturated at 96psi.)

I am working q530 on the 2016 thermal fluids practice exam.  The question is asking for the turning efficiency from State 1 to state 2. At state 1, p=900 psia, T=900F. At state 2, P=96 psia, T= 450. I get h1 = 1452, s1=1.6262 and h2(actual) = 1254 from superheated tables. However, the solution...

@Slay the P.E. Thanks for the explanation!

Hello, I am working through the 2016 thermal fluids practice exam and a couple questions are tripping me up. On Q532, the solution states that steam at 25 psi, 100 DegF has an enthalpy of 68 BTu/lbm. Which specific steam table is this data extracted from? The table I have does not have any...

yg - Where were you able to find the 2001 exam? I have had no luck digging that one up. Thanks
