Hi, I understand you are trying to solve the equation. You can do this using dsolve. Here is a sample code.
clc;
clear all;
syms rho cp T(t) mn V Tin P(t) heff Tamb k
P=k*T; % Ideal Gas Equation
eqn= rho*cp*diff(T,1) + mn*cp*(T-Tin)/V - diff(P,1) + heff*(T-Tamb) ==0;
T_sol=dsolve(eqn);
disp(T_sol);

cp*M*(dT/dt)= - U*A*(T-T_out(t))
In this energy balance I want to plot the temperature profile.
How can I manage the temperature T_out that changes in time?
Thanks!
