In the continuous stirring heating system shown in the figure below, the flow rate of the inflow liquid is wi, the flow rate of the outflow liquid is w, and the volume of the fluid in the heating tank is V The density is , and the amount of heat supplied by the heater is Q. The specific heat of the fluid is Cp.

(2) Through linearization, a linear model composed of deviation variables is obtained, Laplace conversion is performed, and the relationship between T-wi, T-Ti, and T-Q is shown Find the transfer function.
