Hello everyone!
I want to solve this equation in order to plot the theoretical temperature profile T:
I know the value of mass (10000), specific heat (2000), U (120), area (25) and the profile of T_w during time.
The experimental values of temperature T are known:
Thanks in advance!

syms rho cp V u A Tw T0 T(t) Tw(t)
eqn = rho*cp*V*diff(T,t) == u*A*(Tw-T);
cond = T(0)==T0;
T = dsolve(eqn,cond)
T =
