Detailed explanation-1: -To calculate the drying rate, subtract the final moisture content from the initial moisture content, then divide by the time. In this case, the moisture content is presented as a percentage of dry mass, but units of weight of moisture could be substituted.
Detailed explanation-2: -The amount of water is determined by subtracting the dry weight from the initial weight, and the moisture content is then calculated as the amount of water divided by the dry weight or total weight, depending on the reporting method. Even this simple loss-on-drying method is mined with potential variability traps.
Detailed explanation-3: -The moisture correction is made by multiplying the aggregate weight shown by 100 plus the percentage of moisture in the material. If a moisture determination shows that the sand has 5% total moisture, multiply the sand weight shown by 105%.
