Question
Radioactive waters are packed in a long, thin - walled cylindrical container. The wastes generate thermal energy non uniformly according to the following relation: where q = rate of energy generation per unit volume at a distance r from the center Steady - state conditions are maintain by submerging the container in a flowing liquid at 25 degree C and provides a uniform convection coefficient 1000 W/(m2.K). Write the energy balance for this system by using the container as the control volume Plot the surface temperature of the container as a function of the radius of the container(0.2 0.8m) If the surface temperature of the container should be kept below 40 degree C, what is the maxi mu m allowable radius of the container?Explanation / Answer
