    Spring constant of diatomic molecule PbO???

    Hello, I have a problem in relation to the vibration of a diatomic molecule (PbO), but it has been too long ago since I last had chemistry and physics... If I look at PbO as a system of 2 masses and 1 spring (a harmonic oscillator), is there a way to know the "spring constant" of this...

    Radiation of gases

    Hello, I am modelling radiation of a combustion reaction in an industrial furnace. The flame contains besides regular gas species (CO, CO2, H2O, N2,...) also a lot of ash (mainly Zinc oxide) and other more exotic gas species (Zn(g), PbO(g!!)). The temperatures of the flame are around 1600 °C...

    Heat transfer in gas-stirred vessels

    Hello, I am working in the domain of pyrometallurgy and wanted to get someones opinion on the following problem. I am modeling a zinc fuming process for the reduction and evaporation of zinc from a molten slag bath at 1350 °C. In this slag bath, hot blast air and CH4 are injected at the bottom...

    Heat transfer to sidewalls in gas-stirred vessels

    Hello, I am working in the domain of pyrometallurgy and wanted to get the opinion of a chemical engineer on the following problem. I am modeling a zinc fuming process for the reduction and evaporation of zinc from a molten slag bath at 1350 °C. In this slag bath, hot blast air and CH4 are...

    Fortran 90: Tab characters?

    Hello, I have small Fortran 90 question (compaq visual fortran). I want to write a matrix in an output file, and separate each element of the matrix by a "tab-character". I have found the control edit descriptors to make a tab character in fortran output (e.g. TR1, TL1 or T1), but when I run...

    Gas radiation Zn(g), Pb(g), PbO(g)

    Hello, I'm new on this forum but wanted to try with a question on radiation of gases. I'm currently developing a model to estimate radiation of a flame in a "zinc fuming furnace". This is a metallurgical process where ZnO is first reduced and evaporated from a molten slag bath (ZnO_slag -->...
