    States that haven't released yet?

    Did they say when it was mailed out?
  2. I thought the AM was much harder than the PM. I feel like PM was a breeze other than a few off topic questions.

    TFS practice problem of the week...

    What values did you get for the number of moles in H2O and water vapor partial pressure?

    TFS practice problem of the week...

    So for this problem. I need to balance the combustion equation to include H20 so I can find the mole fraction of H20. Then multiply the mole fraction by the gas pressure at 1 atm to find the pressure of water vapor. Then use that water vapor pressure in the steam tables to give use the minimum temperature of the gas exiting the boiler without condensation. Then use the equation (m_gas)(Cp)(750-T_dp) = (m_steam)(h_fg @ 70 F, 50psi) to find the ration of the mass flow rates? Where T_dp is the temperature found using the water vapor pressure of the gas. Is that right?
