T&F two questions.

[dpolet]

I will take T&F afternoon. When calculate fluid loss through a valve, will the equiv.length (ft) be listed in the exam (AM+PM)? I did see this in 2008 ncees sample exam, but I am not sure if this is the general rule.

I have another question about the R134a P-H chart. Will the ncees give such chart during the exam if I take T&F in the afternoon. I want to know how to find a clear printable copy of such chart. I don't have ASHRAE book.

Any suggestion?Thanks.

You could use P-H tables. Mine are in the appendix of a thermodynamics book.

I just did a quick search and found several high resolution examples that you could print, also.

Are you planning to bring the MERM with you? That should have Cv and equivalent lengths of valves and fittings. I wouldn't necessarily count on it being shown on the exam.

Cameron Hydraulic Data is a great reference for Fluids and Fluid Machines as well as a bunch of other general engineering subjects. I prefer it to the Crane TP410. Take it to the exam,

I have a copy from 1984, I assume the newer copies are very much the same.
