1.53 In one stage of an annealing process, 304 stainless steel sheet is taken from 300 K to 1250 K as it passes through an electrically heated  oven  at  a speed of Vs = 10 mm/s. The sheet thickness and width  are ts = 8 mm  and  Ws = 2 m,  respectively,  while the
Â
deactivation? Units of h and (Ts - T) are W/m2 · K
height, width, and length of the oven are Ho
= 2 m,
Â
and K, respectively.
(c)Â Â Â If the heaters are inadvertently activated when the tank is empty, the natural convection coefficient associated with heat transfer to the ambient air at T00 = 300 K may be approximated as h = 0.70 (Ts - T00)1/3. If the temperature of the tank walls is also 300 K and the emissivity of the heater surface is s = 0.85, what is the surface temperature of each heater under steady-state conditions?
