Weight-Volume relationships

Weight is defined as the quantity of matter contained in a body. Weight can also be defined as the force acting on a body due to gravity. Mathematically, weight can be defined as-

Question

3.8 Following CT scanning, data are available for a chalk core plug from the North
Sea area. The core plug is scanned at equal distance for 9 different slices. The
second column provides the CT numbers for a clean sample (denoted as air ref),
whereas the third column provides the CT numbers for a 100% brine-saturated
sample (denoted as water ref). CT number for pure water is 32 HU and -1000
HU for air. Calculate the porosities of each slice of this core plug.
