Hi

i am having alot of trouble with this equation.

H=R*Z*T1*(n/(n-1))*(P2/P1)^((n-1)/n)-1)

n=(log(P2/P1))/(log(P2/P1)-log(T2/T1))

I am trying to get it so the subject is P2 instead of H. If anyone could give it ago or even guide me along the right lines that would be great.

I have tried various things; namely simplifying n before putting it into the main equation. I kept getting confused with all the logs though.

Any help would be great.

Thanks
Matt
