Questions and Answers of Heat And Mass Transfer Fundamentals And Applications

Heat is generated in a long 0.3-cm-diameter cylindrical electric heater at a rate of 180 W/cm3. The heat flux at the surface of the heater in steady operation is(a) 12.7 W/cm2(b) 13.5 W/cm2(c) 64.7
Heat is generated uniformly in a 4-cm-diameter, 12-cm-long solid bar (k = 2.4 W/m·K). The temperatures at the center and at the surface of the bar are measured to be 210°C and 45°C, respectively.
Heat is generated in a 10-cm-diameter spherical radioactive material whose thermal conductivity is 25 W/m · K uniformly at a rate of 15 W/cm3. If the surface temperature of the material is measured
