The image above represents the Urbain and Boiret viscosity model. To calculate the Urbain and Boiret viscosity model, three essential parameters are needed, and these parameters are the Empirical Constant (A), Empirical Constant (B) and Temperature (T).
The formula for calculating Urbain and Boiret viscosity model:
η = AT.exp(1000B / T)
Where:
η = Urbain and Boiret Viscosity Model
A = Empirical Constant
B = Empirical Constant
T = Temperature
Let’s solve an example;
Find the urbain and boiret viscosity model when the empirical constant is 14, the empirical constant is 21 and the temperature is 18.
This implies that;
A = Empirical Constant = 14
B = Empirical Constant = 21
T = Temperature = 18
η = AT.exp(1000B / T)
That is, η = (14)(18).exp(1000(21) / 18)
η = 252.exp(21000 / 18)
η = 252.exp(1166.66)
So, η = 252.(Infinity)
η = Infinity
Therefore, the urbain and boiret viscosity model is infinity.
