The E.M.F (E) in a thermocouple at any temperature T is given as E=0.2...
Given Information:
The EMF (E) in a thermocouple at any temperature T is given as E = 0.2T - 5×10^(-1)T^2, where T is the temperature in degrees Celsius.
Required:
To show that at the steam point (100°C), the thermocouple will generate an EMF (E) of 15mV.
Calculation:
To find the EMF (E) at the steam point (100°C), we substitute T = 100°C into the given equation.
E = 0.2T - 5×10^(-1)T^2
E = 0.2(100) - 5×10^(-1)(100)^2
E = 20 - 5×10^(-1)×10000
E = 20 - 5×1000
E = 20 - 5000
E = -4980mV
Discussion:
The calculated EMF at the steam point is -4980mV. However, the required EMF is 15mV, which is a positive value. Therefore, it seems that there might have been an error in the calculation or the given equation.
Correction:
Upon reviewing the given equation, it appears that there was a mistake in the equation. The correct equation for the EMF (E) in a thermocouple at any temperature T should be:
E = 0.2T - 5×10^(-3)T^2
Let's recalculate the EMF (E) at the steam point (100°C) using the corrected equation:
E = 0.2T - 5×10^(-3)T^2
E = 0.2(100) - 5×10^(-3)(100)^2
E = 20 - 5×10^(-3)×10000
E = 20 - 5×10^(-3)×10000
E = 20 - 50
E = -30mV
Conclusion:
After recalculating using the correct equation, we find that the EMF (E) at the steam point (100°C) is -30mV, which is not equal to the required value of 15mV. This indicates that there might be a mistake in the given equation or some other factor affecting the EMF generation. Further analysis or clarification is needed to determine the correct EMF at the steam point.
