What term refers to a marked loss of bone density and an increase in bone porosity commonly associated with aging?
What is the medical term referring to a marked loss of bone density and an increase in bone porosity commonly associated with aging?
The relationship between density and porosity is an indirect proportionality.That is, the higher the density of a rock, the lower will be the porosity of that rock.In a more explicit way, the weight of over-lying rocks increase the density of the rock beneath, which in turn decreases the amount of pore spaces (porosity) of the rock through processes such as compaction, cementation, etc. Posted by Nwigwudu Ikechukwu.
How do you find porosity of a soil when all you are given is the dry density and the particle density of the soil.. and can you find bulk density with just this info?
Concerning the second Question: "Can you find bulk density with just this info?" Purely on mathematical insight and analysis: Yes, you should be able to find the bulk density of dry soil, given the 'dry overall' and the 'particle' densities. When wet, there is not enough 'given' Also some should be known about the (or your) definition of porosity
Porosity= Volume of void space/ Total volume of the solid This is a good way for soil, If you have the initial volume of the soil then all you have to do to find the void space is saturate it with water. As long as you know the weight different between before and after saturation you can find the void space because we know that water's density is about 1g/cm^3. So, Porosity= ((mass of saturated…
