Ti Ta w Heating coil - T lelll
A completely enclosed stirred-tank heating process isused to heat an incoming stream whose flow rate varies.The heating rate from this coil and the volume are both constant.(a)Develop a mathematical model (differential and algebraic equations) that describes the exit temperature if heat losses tothe ambient occur and if the ambient temperature (Ta)and the incoming stream’s temperature (Ti) both can vary.(b)Discuss qualitatively what you expect to happen as Ti and w increase (or decrease). Justify by reference to your model. ρ and Cρ are constants.U, the overall heat transfer coefficient, is constant.As is the surface area for heat losses to ambient.Ti>Ta(inlet temperature is higher than ambient tempera-ture).
