Question
Chapter 2, Problem 1EDDS
To determine
Explain how to characterize the NSPE definition of sustainability.
Explain on what the philosophy of sustainability relies upon, and also explain its impact on civil engineering projects that have sustainability as a design goal.
Expert Solution & Answer
Explanation of Solution
The NSPE (National Society of Professional Engineers) defines sustainability as “the challenge of satisfying human needs related to industrial products, natural resources, food, energy, shelter, transportation, and effective management of waste, and also conserve and protect environment quality and natural resources base necessary for future development.
According to NSPE, sustainability is characterized by integration of development and conservation as well as satisfying basic human needs.
The philosophy of sustainability mainly depends upon the conservation of the available resources. In the case of civil engineering, sustainability is referred to as the conservation of construction material in an environment-friendly manner.
In construction projects such as roads, buildings, and sewage treatment plant, the design and construction should be done in such a way that its impact on the environment is minimum and it also reduces global warming.

- Problem 4. A major transmission pathway of the novel coronavirus disease 2019 (COVID- 19) is through droplets and aerosols produced by violent respiratory events such as sneezes and coughs (Fig. 1). For the purpose of providing public health guidelines, we would like to estimate the amount of time it takes for these droplets to settle from air to the ground. The relevant parameters are the settling time (ts), the initial height of the droplets (H), gravitational acceleration (g), density of the droplets (pa), radius of the droplets (R), as well as dynamic viscosity of the ambient air (Pair). Use dimensional analysis and the Buckingham theorem to answer the following questions: 1. Find the independent dimensionless parameters using the table method. Then, express the settling time as a function of the other relevant parameters. Your solution should match the physical intuition that the settling time scales linearly with the initial height. 2. How would the settling change if the…arrow_forwardQuestion 4 An engineer is assigned to design a 25-stories office building which has a building height of 75 m.

The clay layer is located below a 3.5 m thick granular fill (p= 1.8 Mg/m³). A dense sandy gravel is found below the clay. The groundwater table is located at the top of the clay layer, and the submerged density of the clay soil is 0.95 Mg/m³. Consolidation tests performed on 2.20 cm thick doubly drained samples indicate the time for 50% consolidation completed as t50 = 10.5 min for a load increment close to that of the loaded clay layer. Compute the effective stress in the clay layer at a depth of 16 m below the ground surface 3.5 years after the application of the load.arrow_forward13-3.
