The rate of flow of heat through a metal rod with temperature difference 40 is 1600 cal/s. The thermal resistance of metal rod in s/cal is (a) 0.025 (b) 0.25 (c) 2.5 (d) 40

Answer: (a). Thermal resistance R = (Δ T)/(H) R = (40)/(1600) = 0.025 s/cal So the answer is (a) 0.025.

Heat Conduction

The rate of flow of heat through a metal rod with temperature difference $40^\circ\text{C}$ is $1600\text{ cal/s}$ . The thermal resistance of metal rod in $^\circ\text{C s/cal}$ is

Show answer and solution

Answer: (a)

Thermal resistance $R = \frac{\Delta T}{H}$
$R = \frac{40}{1600} = 0.025\ ^\circ\text{C s/cal}$
So the answer is (a) 0.025.
