20) The temperature of a turkey in an oven is assumed to be uniform throughout the orra, and neglecting the heat absorbed by the cooking reactions, is given by the following differential equations: MCdT/dt=A[Tov4T4] where M is mass of the turkey, C is its specific heat, is the Stephan-Boltzmann constant equal to 5.67108W/m2K, is the emissivity of turkey skin equal to 0.65,A is the surface area of turkey, T is the temperature of the turkey in K and Tov is the oven temperature in K. (a) Make a linear approximation to the differential equation and obtain the transfer function G(s)=T(s)/T ov (s) (b) For M=10kg,C=2.85kJ/kgK,A=0.3m2, calculate the steady state gain and the time constant of the transfer function
