The density of a substance can be found by dividing its mass by its volume. As long as a substance is homogeneous, the size or shape of the sample doesn’t matter. The density will always be the same. This means that a steel paper clip has the same density as a steel girder used to build a bridge. Density = Mass ÷ Volume D =

Note: Many of the approaches taken are somewhat arbitrary and there would be wide range for suitable approaches with different answers. Below is just one of what could be a suitable solution. 1. a) Calculate the gross specific area (m2/m3) in a sand filter with sand nominal diameter 0.4 mm and porosity 0.4.
