Q5: Heat is often generated by blowing air through a coil of wire that conducts an electric current in a dryer. The thermal energy generated by the electrical resistance heating in the wire is then released by convection from the surface of the wire to the environment. T-Ti@t-0 (Note: Assume room temperature) a) Show the system schematically and state the assumptions. b) Write down the boundary/initial conditions that determine the transient thermal response, T(r, t), of the wire. c) Calculate the volumetric rate of thermal generation (Note: Power consumption (Pelec) 750 W, L=600 mm and r=1.2 mm). d) Calculate the convection heat flux at steady- state conditions?
