MathCAD - Help Please!!

[0209781l]

Hi All,

I am an inexperienced MathCAD user (or rather I have not used it for many years) and i am trying to interpolate using the known value 'pm/py' and linearly solve this to calculate 'Pr/Py' from the matrix.

Once pr/py is calculated i would then like to solve this using the known value py = 3.755MPa.

Can anyone please advise how I go about this using MathCAD? Any assistance would be much appreciated.

many thanks

The actual worksheet is preferable to a picture of one.

Nevertheless, you have the following obvious problems
> a ratio of variables cannot be used as a variable name, since Mathcad wants to evaluate the ratio -- you could possibly call it "p.m_p.y" insgtead
> the triple equal sign is a pre-processed assignment operator, and cannot used in assignments of calculations that occur later in time.

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!
