1. An air-dry soil with a moisture content of 25% by weight is to be used in a experiment. If each pot is to have 30kg oven-dried soil, how much of the air-dry should be weighed into the pot and how much of that moisture in kg? Show calculati 2. A soil sample was taken with a cylindrical metal core having a volume of 300cm3 soil was saturated with water and then drainage water was allowed to drip. Meanw the evaporation of water from the soil was prevented. The drained soil sample weig 500g before oven-drying and 350g after oven-drying. Calculate the following: a. Bulk Density b. MC% by weight and volume c. Porosity(assume Dp-2.65g/cm') d. cm of water per 100cm depth of soil (depth of water in cm = MC% by volt x depth of soil) Show calculations.
