Type 10 nomogram code for Pynomo software. Van Der Waals equation

This is a python-based code to be run under PyNomo software to construct a type 10 nomogram for Van Der Waals chemical equation, knowing that it has the following expression:

\(\left({p+{{a}\over{v^{2}}}}\right)\ast\left({v-b}\right)=R\ast\left({t+273.15}\right)\)

which represents a mathematical function of the form (Type 10 nomogram): 

\(f_{1}\left({u_{1}}\right)+f_{2}\left({u_{2}}\right)\ast f_{3}\left({u_{3}}\right)+f_{4}\left({u_{3}}\right)=0\)
