Odesolve 1st order single ODE

Odesolve 1st order single ODE

Odesolve 1st order single ODE

(OP)
Hello,

I am trying to use Odesolve to solve a single 1st order ODE for the boundary layer thickness (delta) as a function of (x), with the single boundary condition of delta(0)=0. I believe I have the Solve Block setup correctly, but I am getting a units error. The units of the result should be length. If I make all parameters dimensionless, I then get an error "divide by zero". I am a little confused and obviously don't use Odesolve as much as I should.

I have attached my Mathcad sheet.

Thanks for any help!

I found one typo. The upper limit of the integration should be "L" or "4 meters" instead of "4".
