NEEd HELP!! Preparing for final

Be sure to include appropriate units in your calculations and answers. Estimate the area and volume of landfill to handle the solid waste from Midden for 20 years. Assume a cell height of 2.40 m and that the recommended depths of cover will be used and mat compaction will be normal. The Science Club at Midden High School has furnished the data based on a 12-month survey. (One sample having a mass of 1.000 Mg was taken at the existing landfill during normal off-loading operations 1. day each month.) The average solid waste generation rate in Midden (population 44.000) is 1.17 kg/cap d and the average uncompacted density is 144.7 kg/m3. Each residence has two pickups per week (maximum of 4 days between pickups) and that there are no rear-of-house pickups. 12 trucks with a capacity of 9m3 are used by the waste pick-up contractor for the routes and are based on the following information: Truck compactor density rating = 475 kg/m3 Truck dump time = 7.50 min Delay time = 20.0 m
