Function of function with units

Dear members of the mathcad community,

 

I want to define a function within a function by considering the units of measurement.

The function looks like g(f(x))= f(x)*a where "a" is a parameter.

I know that there are other posts on the topic but unfortunately I could not solve the problem.

Attached you find an example of my calculation.

I would really appreciate your advice.

Thank-you very much.

 

Best regards.

 

Enrico

Can't see your file, as I don't have Mathcad 15. Maybe you could save as Mathcad 11 (.mcd)...

But this may be of help.

 

Success!

    Put the pressure function as the argument of the force:

     

    F(p(a))

    Hi,

     

    There is also a small issue you should be aware of called "Vectorize".

    This is applying a function to a column vector in an element by element fashion.

    Look it up in help.

     

    It does not apply to the equations in your sheet, but you should be made aware with different definitions it may be necessary.

     

    Regards

    Terry
