Extracted text: Q6/ The contents of the stirred-tank heating system shown in Fig. E4.10 are heated at a constant rate of Q(Btu/h) using a gas-fired heater. The flow rate w(lb/h) and volume V(ft³) are constant, but the heat loss to the surroundings Q(Btu/h) varies with the wind velocity v (ft/s) according to the expressions: Q. = UA(T – T.) and U(t) = U + bv°(t) where U, A, b, and Ta are constants. Derive the transfer function between exit temperature T and wind velocity v. List any additional assumptions that you make. %3D w V Ta T ellllld w Q Figure E4.10
