Given the following soil properties, find the % of water by weight at soil saturation with water:
Moist sample weight: 202.16
Oven dry sample weight: 197.8
Bulk Volume:118.86
Particle Volume Density: 73.73
Soil bulk density: 1.66
soil particle density: 2.68
% pore space: 38.06
% water by weight: 2.24025
% water by volume: .0225
% of airspace at the time of sampling: 35.86
% water by weight at saturation with water: ?
To find the % of water by weight at soil saturation with water, we can use the following formula:
% water by weight at saturation = ((moist sample weight - oven dry sample weight) / oven dry sample weight) x 100
Given the values you have provided, we can plug them into the formula:
Moist sample weight: 202.16
Oven dry sample weight: 197.8
% water by weight at saturation = ((202.16 - 197.8) / 197.8) x 100
= (4.36 / 197.8) x 100
= 0.0220 x 100
= 2.20%
Therefore, the % of water by weight at soil saturation with water is approximately 2.20%.
