Determination of suspension density
Thread Content
It is a water-insoluble solid particle with a true density of 2320 kg/m3 and a bulk density of 185 kg/m3. When 500 kg of such solid particles are mixed with 1000 kg of water thoroughly, how should the density of the mixture be calculated?
The volume of 500 grams is calculated based on its true density; the result is obtained by dividing the total mass of water, which is 1500, by the total volume of 1000 grams of water.
Is it determined that the true density should be used to calculate the volume of solid particles, rather than the bulk density?
Isn’t density mass divided by volume? Is there any doubt about this?
