How to Calculate and Solve for Apparent Porosity | Refractories

The apparent porosity is illustrated by the image below.

To compute for apparent porosity, three essential parameters are needed and these parameters are Soaked Weight (W), Dried Weight (D) and Suspended Weight (S).

The formula for calulating apparent porosity:

AP = 100((W – D)/(W – S))

Where:

AP = Apparent Porosity
W = Soaked Weight
D = Dried Weight
S = Suspended Weight

Let’s solve an example;
Find the apparent porosity when the soaked weight is 14, the dried weight is 10 and the suspended weight is 12.

This implies that;

W = Soaked Weight = 14
D = Dried Weight = 10
S = Suspended Weight = 12

AP = 100((W – D)/(W – S))
AP = 100((14 – 10)/(14 – 12))
AP = 100(4/2)
AP = 100(2)
AP = 200

Therefore, the apparent porosity is 200%.
