Default Itratie formule

Goedendag
ik heb deze formules

r=(d)/4 -------------1
c=18log(4*(d)/0.001) ------------2
v1=c*(WORTEL(r*i)) -------------3

i is bekend

als ik d in formule 1en 2 en 3 invoegen dan kan ik v1 rekenen


a=(3.14*((d)^2))/4-------------------4
v2=q/a ------5

q is bekend

als ik d in formule 4 invoegen ,dan kan ik v2 rekenen van formule 5

wat ik wil dat ieder keer een d ingevoerd tot dat v1=v2
de d waarde is tussen 0,050 tot 1,500
beginwaarde is 0,050 en mag vermeerden tot dat ik de goed (d) krijg

graag uw reactie...
