Question
Exercise. Calculate porosity. We need: Beaker (100ml) Graduated cylinder (50ml) Coarse and find sand Water Step1: fill the beaker up to the 80mlmark with fine sand Step2: slowly pour the water into the sand filled beaker, allowing time for water to seep through the sediments, until the water reaches the 80ml mark of the beaker Step3-determine how much water has been added to the sediment in order to fill up all of the pore spaces. (50ml-remaining water=volume of pore space) Step4: calculate the porosity of the fine sand as a percentage of the total volumeReading=18ml Exercise. Calculate porosity.

Reading=18ml
Explanation / Answer
Porosity = Volume of liquid/gas/ ( Total volume of solid + volume of liquid/gas )
Therefore Porosity = 18/( 80) = 22.5 %
