Explanation of Solution

The statement that includes a comparison of the total generation and percentage compared to the national averages is as below.

The national average of the waste above the percentage of the waste refuse produced by a single person in the house is 200 per cent and the waste coming out of a family of 5 members is about 10.25lb/person .

The weights of solid waste are classified below.

    Weight(lbs) Per cent of the total weight
    Paper 9.0 17.5
    Plastics 6.0 11.70
    Aluminium 4.0 7.80
    Steel <1.0 <1
    Glass   28.75 55.60
    Food 3.5 6.82
    Other <2.0 <1
    Total   51.25 100

About 8.56lb/day waste is generated by a per person according to the (EPA) Environmental Protection Agency’s 2018 facts and figures assessment.

To determine

(b)

The amount of waste that is reusable and to identify the amount of waste that might be reduced.

Expert Solution

Explanation of Solution

Glass waste can be reused in various ways such as mixing the glass powder with concrete for the replacement of sand. Since the demand for sand is more, glass powder can be used as a partial replacement for sand. Plastic bags can be used as plastic bottles; supply cups can be used for keeping pens, pencil and the plastic watering cans can be used as pots for gardening.

To determine

(c)

The various items in the refuse that is recoverable and to identify the process that is carried out.

Expert Solution

Explanation of Solution

Recovery is defined as process by which the refuse can be converted into new products. Recovery of the materials such as waste plastic bottles can be converted to new plastic bottles, steel cans are converted to new steel cans, steel beams or recycled bicycles.

Consider a pool of saturated water at atmospheric pressure. The base of the pool is made of thick polished copper square plate of length 1 m. To generate steam, exhaust gas is flowing underneath and parallel to the base plate with velocity 3 m/s and average temperate of 1090°C. The bottom surface the plate is at constant temperature of 110°. Use the properties of air for exhaust gas. a) Determine the boiling heat transfer rate. b) Determine the temperature of the top surface of the plate. Comment on the results. c) Examine the impact of your assumptions on your solutions. (what will change if any of the assumptions is not valid?)

1. For the foundation shown below: Qapp = 60 kips (Load obtained from structural engineer) 1.5 ft G.W.T. 3 ft Poorly Graded Sand (SP): Ym 115 pcf (above G.W.T.) Ysat 125 pcf (below G.W.T.) c' = 0, ' = 35° K Square footing, 4' x 4' Foundation Dimension Information: 1-ft x 1-ft square concrete column. 1-ft thick "foot" flanges. Yconc=150 pcf *Assume weight of reinforcing steel included in unit weight of concrete. *Assume compacted backfill weighs the same as in-situ soil. Assume this foundation is being designed for a warehouse that had a thorough preliminary soil exploration. Using the general bearing capacity equation: a. Calculate the gross applied bearing pressure, the gross ultimate bearing pressure, and determine if the foundation system is safe using a gross bearing capacity ASD approach. Please include the weight of the foundation, the weight of the backfill soil, and the effect of the uplift pressure caused by the presence of the water table in your bearing capacity…
