The document I attached is a short blurb of what I did on a problem I couldn't solve. I did everything I could I still got it wrong and I have no idea why. I was wondering if someone could show me. The differential equations are modeling the the heat balances the the pipe and slurry while immersed in a temp. maintained oil bath at 200C

I did the calculations and the graph in matlab I uploaded that as well.

values of constants:

Mp=300g

Ms=20g

Ao=80cm^2

Ai=70cm^2

Cp=.5J/g*C

Cs=4J/g*C

Ho=.05 W/cm^2*C

Hi=.04 W/cm^2*C

temp at time zero= 25C

temp of oil immersion (To)=200C

Ts=temp of slurry

Tp=temp of pipe
