I did passed TFS in October. Thanks everyone for the help, support and encouragement from Forum. I am out of school more than 10 years and I spent around 350-400 hours for the PE test. I exactly followed the study strategy from Ramnares P.E the material I used: MERM (read all TFS sections...

Thanks :D

You are correct. I used Mollier diagram to find h exit. I wondering why this happened?

A steam power plant operates at maximum pressure of 500 psia and a low pressure value of 14.7 psia. All of the steam is extracted from the turbine at 60 psia and is reheated back to maximum temperature. The maximum temperature is 1000 f. What is the work out put at the turbine.? Assume the...

In Some steam turbine problem, when using entropy calculate turbine outlet enthelpy.  The quality x>=1. Is this correct? I thought the quality must always be less 1. 

Thank you again for your help

Thanks. The head loss in each breach is same. Am I right?

For the parallel pipe flow system, the friction head loss should be equal in each branch?

Solution: the minimum required differential pressure is equal to the sum of the losses through a control valve and AHU. the 10 ft of water pressure loss through the AHU must be converted to psi.  Coil pressure drop= 10 ftX0.433 =4.33 psi adding this value to the design control valve loss of 5...

Thank you for your reply!

Can anyone share the thinking process for this problem? I review the solution and sort of get the answer, but not clear. Appreciate any feedback.

Thank you very much for the details :D

Thank you Slay for the explanation. when do I need use the compressed liquid table?

hc=378.3 btu/lbm and hd=85.8 btu/lbm. is this based on the steam table saturated water at 110F and 400F? the table shows 78.02 btu/lbm and 375.1 btu/lbm at 110f and 400f.

Thank you Mike
