CBT - Mech Reference Errors

[Mech Uruk Thraka]

Beware, NCEES provided reference manual has errors in their steam table. 

Saturation pressure of water at 65F should be 0.3. See http://www.che.ksu.edu/docs/imported/SteamTable.pdf, https://www.engineeringtoolbox.com/water-vapor-saturation-pressure-d_599.html?vA=65&units=F#, and/or https://www.slaythepe.com/uploads/7/2/3/9/72392189/water-steam_saturation_properties__by_temperature_in_us_units_.pdf for supporting documents. 

Additionally, we should be able to recognize the provided chart as incorrect as pressure is directly proportional to the temperature

Good catch.

It appears that of the highlighted values, only the one for 64F is incorrect (it should be 0.3 psia). Did you report this to them?

I have.

I have. 

OK, thanks.
