Hi all,

I am new to Mathcad and started working on the rate based model.

I am trying to solve this through the above assumptions.

I am Assuming Kgprime for MEA/CO2/H2) from an experimental study and calculating the ncO2, nH2O, h and q

Using the following relation.

Function calculating gas and liquid outlet molar flow rate and enthalpy for a given amount of mass transfer of CO2, H2O and heat transfer (MW) (fo)

and foa.

any help would be great thanks

Lisa

Your file needs Mathcad file 97stm.mcd (contained on your M drive) in order to work. Since you haven't attached this, your file won't work for those of us who don't have access to your M drive. You could either upload 97stm.mcd, or extract the functions your program needs and include them explicitly in the worksheet. Then we will stand a better chance of helping.

Ok. Your problems stem from the fact that M15 (and earlier) won't accept variables with different units in the same vector - see attached.
