The image of larson – miller parameter is represented below. To calculate larson – miller parameter, three essential parameters are needed and these parameters are Constant of Order 20 (C), Temperature (Kelvin) (T) and Lifetime (Hours) (tr).
The formula for calculating larson – miller parameter:
LM = T(C + log tr)
Where:
LM = Larson – Miller Parameter
C = Constant of Order 20
T = Temperature (Kelvin)
tr = Lifetime (hours)
Let’ solve an example;
Find the larson – miller parameter when the constant of order 20 is 10, the temperature is 4 and the lifetime is 8.
This implies that;
C = Constant of Order 20 = 10
T = Temperature (Kelvin) = 4
tr = Lifetime (hours) = 8
LM = T(C + log tr)
LM = (4)(10 + log(8))
That is, LM = (4)(10 + (0.90))
LM = (4)(10.90)
LM = 43.61
Therefore, the larson – miller parameter is 43.61.
