engineering recuitment HPCL Engineer Mock Test 2024 Heat Transfer Conduction Heat Conduction Through Hollow and Composite Cylinders
Two hollow cylinders identical in size have same temperatures on their inner surface and outer surfaces but different thermal conductivities. If the ratio of thermal conductivity of 1st cylinder to 2nd cylinder is 2:1, then at a distance r from the inner surface,
1
Temperature of cylinder 1 > Temperature of cylinder 2
2
Temperature of cylinder 1 < Temperature of cylinder 2
3
Temperature of cylinder 1 = Temperature of cylinder 2
4
