The City of Forty-Five (population 465,565) has requested your assistance in evaluating its solid waste collection system. Determine the mean time per collection stop plus the mean time to reach the next stop, the number of pickup locations per load, and the minimum number of trucks the city must own. The City of Forty-Five collection data are as follows: Average truck capacity = 12.5 m3; Average observed compaction ratio = 2.87 Crew size = 2; Number of pickups = 1 /wk (no rear-of-house service) Average number of cans per stop = 2.63/wk at 0.1136 m3/can Average number of residents per stop = 5 Average uncompacted density = 105.76 kg/m3 Average transport time to disposal site including delays and dumping = 1.78 h/trip Average number of trips to disposal site = 2/d; Rest breaks = 2 at 28.0 min Average maintenance downtime = 37.0 min/d; Average workday = 8.00 h Average percent of trucks out of service for major repairs = 15.0% Number of workday per week = 5

A sample of water is to be analyzed for solids content. Ten liters of water are passed through a filter (initial weight of filter is 15 grams). After drying at 105 C, the filter plus residual weighs 43 grams. Another 10 liters of sample of the same water is evaporated, without filtering, yielding a residual mass of 40 grams. The result of the analysis is calculated as follows: a. Total Solids of this water is--- b. Suspended Solids is--- c. Total Dissolved Solids (TDS) is- -Grams per liter. -Grams per liter. -Grams per liter. Please Note: The purpose of this problem is for you to understand the difference between Total Solids, Suspended Solids and Total Dissolved Solids. Also pay attention that the units as the sample is 10 liters and the problem is asking you to calculate the values per liter.
