Studiot / Bender, Thank you for your help and ideas. I understand the problem I've got on hand is a very complicated one, and is probably a little time consuming to calculate instead of simply experiment to get some bases. Below I've included a picture of what such facility looks like. Except the one below the soil depth is 1 meter instead of 2. Much appreciated.

Hi, Recently I was faced with a challenge to find out how long it might take for moisture concentration to reduce from 80% to 30% for soil, under constant sifting/turning . Here is the cenario. I have a tunnel of 80 meters, width of 4 meters. depth of 2 meters. daily, wet soil will be delivered to the front end of the tunnel and everyday, or given a set period there is a machine that mulch/mix and flips the soil backwards by 1 meter. The constants are: Input soil: 10 cubic meters, 80% water content. Machine: has blade that mixes the soil and flip it backwards by 1 meter. The bed of the tunnel is heated to 50 deg c, can assume the entire soil mass is about 45 deg C Air temperature is 25 deg C, zero wind speed as it is indoors. The tunnel has access to sunlight, but not sure how much it will contribute since i have no way of measuring sunlight's heat or energy generated. should look like | [Machine] | |~~~////~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| |___////_______________SOIL_________________________________________________________________| Would like to know how long will it take 'distance' for the soil's moisture content to drop to 30%. I've tried my best searching for a correct formula to use, but couldn't find one for soil, and then using water evap formula for swimming pool has got me very strange results. Please help and thank you in advance. Stv
