I started with this equation and have split it into the following coupled equations:
dT/dx=z
dz/dx= hp/kAc - (T-Ta)

T and x are the unknown variables
I need help transferring this into excel using Eulers method and/or 4th order Runge kutta

Thnaks for any help

Have you decided about the domain of solution?

Have you decided on a step-size?

You don't have a problem you can solve using Euler's method, Runge-Kutta, or any numerical method because you don't have an initial condition from which to start!
