發問:
A sample of partially saturated sand had a volume of 72x10^-6 m^3 and a mass of 0.113 kg. After oven drying, its mass was 0.091kg. Calculate the degree of saturation, moisture content, void ratio and porosity of the sample. Assume Gs=2.68.我想問,,,點計到Vv,,,姐係個volume of void... 條式係Vv=Va+Vw...... 顯示更多 A sample of partially saturated sand had a volume of 72x10^-6 m^3 and a mass of 0.113 kg.
