The figure below shows a hollow sphere made of a material with a temperature-dependent conductivity. The conductivity of the material is given by: k=bT where b = 0.01 W/m-K and T is the temperature in K. TH Tc Tout The sphere is used to contain liquid neon; therefore, the inner surface of the sphere at rin = 2 cm is held at Tc = 30 K. The outer surface of the sphere is exposed to ambient temperature; therefore, the temperature...
In a food processing facility, a spherical container of inner radius n = 40 cm, outer radius r2 = 41 cm, and thermal conductivity k = 1.5 W/m 'C is used to store hot water and to keep it at 100°C at all times (see Figure Q2). To accomplish this, the outer surface of the container is wrapped with a 500-W electric strip heater and then insulated. The temperature of the inner surface of the container is observed to be...
Two large parallel plates with surface conditions approximating those of a blackbody are maintained at 800°C and 100°C, respectively. Determine the rate of heal transfer by radiation between the plates in Wim and the radiative heat transfer coefficient in W/m K ) 12 Write down the one-dimensional sent heal conduction equation for a plane wall with constant thermal conductivity and heat generation in its simplest form, and indicate what each variable represents 13 Write down the one-dimensional transient heat conduction...
Problem 4 Consider a thin-walled cylindrical vessel of unit length, containing volatile solid reactants (specific gravity of 1.5, specific heat capacity of 2200 J/kg-C), which are initially at a temperature of 25° C. The reactants are suddenly stirred thoroughly, and they react endothermically, with a heat generation rate of of 101 W/m3. The inner and outer radius of the thin annulus, made of a material whose thermal conductivity is 12 W/mK, are 0.2-m and 0.215-m, respectively. The vessel is surrounded...
