In Section 5.2 we noted that the value of the Biot number significantly influences the nature of the temperature distribution in a solid during a transient conduction process. Reinforce your understanding of this important concept by using the ¡HT model for one-dimensional transient conduction to determine radial temperature distributions in a 30-mm-diameter, stainless steel rod k = 15 W / m ⋅ K , ρ = 8000 k g / m 3 , c p = 475 J / k g ⋅ K , as it is cooled from an initial uniform temperature of 325°C by a fluid at 25°C. For the following values of the convection coefficient and the designated times, determine the radial temperature distribution: h = 100 W / m 2 ⋅ K t = 0 , 100 , 500 s ; h = 1000 W / m 2 ⋅ K t = 0 , 10 , 50 s ; h = 5000 W / m 2 ⋅ K t = 0 , 1 , 5 , 25 s . Prepare a separate graph for each convection coefficient, on which temperature is plotted as a function of dimensionless radius at the designated times.
