    Calculation of actual spray angle and coverage

    Hey, I am attempting to figure out the optimal nozzle placement for an evaporative cooling tower. Now, calculating the theoretical coverage of each nozzle is obviously not a problem since I know the spray angle of the nozzles. However, since the water is injected at a much higher speed than...

    Equilibrium modelling in kraft mills

    Hi, I've been working with equilibrium modelling in bleach plants of kraft mills in order to find areas likely of being subjected to mineral scale deposits. This has been rather successful - and it's been done successfully be many people before me. However, now I am interested in applying...

    Standard enthelpy of formation needed for EDTA metal complexes

    I just automatically included all the ions of significant concentration. But you are right, the formation constants of Na and K are very low in comparison to other metals such as Ca and Mg - and they can probably be neglected. I'll try this and see how it works out. Thanks!

    Standard enthelpy of formation needed for EDTA metal complexes

    Hi, I am trying to solve the chemical equilibria in a kraft mill bleach plant to predict mineral scale deposits. I am using the van't Hoff equation to account for temperature dependence of the formation constants, but I need the enthalpy of reaction for all equilibria and I am missing some...
