Que. | A hollow sphere (k = 30 W/m K) of inner radius 6 cm and outside radius 8 cm has a heat generation rate of 4000000 W/m³. The inside surface is insulated and heat is removed by convection over the outside surface by a fluid at 100 degree Celsius with surface conductance 300 W/m² K. Make calculations for the temperature at the outside surfaces of the sphere |
a. | 105.6 degree Celsius |
b. | 205.6 degree Celsius |
c. | 305.6 degree Celsius |
d. | 405.6 degree Celsius |
Correct Answer:305.6 degree Celsius
