What is porosity (percentage of void) of powder bed? HMK-22 Fisher Sub Sieve Sizer
What is porosity (percentage of void) of powder bed in a fisher sub sieve sizer?
-There are spaces among particles in powder bed, as a result the space 1cm³ of true density particles actually occupies is more than 1cm³ . If it is 1.25cm³ , then the filling degree is 1/1.25=0.8 and therefore the powder bed porosity is 1-0.80=0.20.
