hello all,

i have a following equation which is attached to this post:

i have a graph, on x axis is ω and on y axis is T. cp,a, cp,v, Ra, To and ωo are known... I want to draw lines on graph with values ex=0.1, ex=0.2, ex=0.3,... so i have to get values for T as a function of ex and ω... how could I get them? i now i have to solve equation with iterations but i do not know how... any ideas?

i hope i was clear what i want to do...

thanks for help!
