The image above represents the viscosity for metallic alloys. To calculate the viscosity for metallic alloys, six essential parameters are needed and these parameters are Viscosity of Metal (η), Interatomic Distance (δ), Avogadro’s Number (NA), Atomic Weight (M), Gas Constant (R) and Temperature (T).
The formula for calculating viscosity for metallic alloys:
η* = ηδ²NA / √(MRT)
Where:
η* = Viscosity for Metallic Alloys
η = Viscosity of Metal
δ = Interatomic Distance
NA = Avogadro’s Number
M = Atomic Weight
R = Gas Constant
T = Temperature (Kelvin)
Let’s solve an example;
Find the viscosity for metallic alloys when the viscosity of metal is 4, the interatomic distance is 12, the avogadro’s number is 6.023e+23, the atomic weight is 9, the gas constant is 2 and the temperature is 5.
This implies that;
η = Viscosity of Metal = 4
δ = Interatomic Distance = 12
NA = Avogadro’s Number = 6.023e+23
M = Atomic Weight = 9
R = Gas Constant = 2
T = Temperature (Kelvin) = 5
η* = ηδ²NA / √(MRT)
η* = (4)(12)²(6.023e+23) / √((9)(2)(5))
So, η* = (4)(144)(6.023e+23) / √(90)
η* = 3.469e+26 / 9.486
η* = 3.65e+25
Therefore, the viscosity for metallic alloys is 3.65e+25 m²/s.
