railway RRB JE (CBT I + CBT II) Mock Test 2024 Heat Transfer Conduction Conduction with Uniform Heat Generation
Heat is generated uniformly in a 4 cm diameter, 16 cm long solid bar [k = 24 W/m°c]. The temperatures at the centre and the surface of the bar are measured to be 210°C and 45°C respectively. The rate of heat generation within the bar is,
1
240 W
2
1013 W
3
7962 W
4
3.96 × 106 W
