Determining the temperature of a rail with given resistance

2023-12-26 09:42:08

To determine the temperature of the rail, we can use the formula T = (R2 - R1) / (R1 * α * A) + 273; where T is temperature in Kelvin, R2 is the new resistance (77 * 10^2 = 7700), R1 is the initial resistance (0.14 * 10^-1 = 1.4), α is the temperature coefficient (3310 K-1) and A is the cross-sectional area (50 * 10^-4 m2).

Plugging in these values, we get T = (7698.6) / (1.4 * 3310 * 50 * 10^-4) + 273 = 552.21 K or 279.06°C. This means that the temperature of the rail is approximately 6°C.

This calculation is based on the assumption that the rail is made of pure steel and that the temperature coefficient remains constant. Furthermore, it is important to note that the actual temperature of the rail may differ slightly due to external factors such as humidity and air temperature.

Overall, to accurately determine the temperature of the rail, it is best to use temperature sensors specifically designed for this purpose. These sensors can provide precise readings and eliminate any potential errors in calculation.
