What is the main goal of sustainability in an engineering context?
Maximize short-term profits regardless of impact
Use only new materials in production
Minimize environmental impact while maintaining performance
Avoid all environmental regulations
Sustainability in engineering seeks to balance environmental protection with technical and economic performance. This ensures resources meet present needs without compromising future generations.
What does pH measure in an environmental sample?
Dissolved oxygen content
Hydrogen ion concentration
Water turbidity
Temperature
pH is a measure of the hydrogen ion concentration in a solution. It indicates acidity or alkalinity on a scale from 0 to 14.
Which gas is considered a primary air pollutant?
Sulfur dioxide (SO2)
Methane (CH4)
Ozone (O3)
Nitrogen gas (N2)
Sulfur dioxide is directly emitted from sources like combustion processes, making it a primary pollutant. Ozone forms later via chemical reactions in the atmosphere.
In data analysis, what is the purpose of a scatter plot?
Measure central tendency
Display average values only
Show relationship between two variables
Rank categorical data
A scatter plot visually depicts the relationship or correlation between two continuous variables. It helps identify trends, clusters, or outliers.
Which fundamental principle ensures structural stability by distributing loads evenly?
Stress distribution
Le Chatelier's principle
Entropy maximization
Bernoulli's principle
Stress distribution refers to designing structures so that loads are spread evenly to prevent failure. Other principles listed are unrelated to structural load distribution.
If a facility reduces its annual CO2 emissions from 1000 to 700 metric tons, what is the percentage reduction?
30%
3%
70%
300%
The reduction is (1000 - 700) / 1000 = 0.30 or 30%. This calculates the proportion of emissions cut relative to the original value.
A bar chart shows emission levels increasing from 50 to 100 units over 5 years. What is the average annual increase?
50 units per year
10 units per year
200 units per year
5 units per year
The increase is 100 - 50 = 50 units over 5 years, so 50 / 5 = 10 units per year. This evenly distributes the change over the period.
Which regulation primarily sets national ambient air quality standards in the United States?
Resource Conservation and Recovery Act
Endangered Species Act
Clean Air Act
Safe Drinking Water Act
The Clean Air Act establishes national standards for ambient air quality. The other acts address waste management, drinking water, and species protection.
Which example best describes non-point source water pollution?
Spill from an oil tanker
Leak from an underground storage tank
Runoff from agricultural fields
Discharge from a wastewater treatment plant
Non-point source pollution comes from diffuse sources like agricultural runoff. The others are point sources with identifiable discharge points.
What is the main purpose of a life cycle assessment?
Assess employee training
Quantify environmental impacts across all product stages
Calculate product cost only
Evaluate market demand
Life cycle assessment evaluates environmental impacts from raw material extraction to disposal. It is not focused on cost or market analysis.
A process inputs 200 kg of raw material and outputs 50 kg of waste. What percentage of the input is converted to product?
25%
50%
75%
200%
If 50 kg is waste, then 150 kg is product. The conversion rate is 150/200 = 0.75 or 75%. This reflects product yield from input materials.
Compared to a coal-fired power plant, a wind turbine generally produces:
Higher sulfur dioxide emissions
More deforestation
Lower lifecycle CO2 emissions
Greater water pollution
Wind turbines have near-zero operational CO2 emissions over their lifecycle. Coal plants emit significant CO2, SOâ‚‚, and other pollutants.
Which technique is most appropriate to remove nitrates from drinking water?
Sedimentation
Ozonation
Ion exchange
Chlorination
Ion exchange resins selectively remove nitrate ions. Chlorination and ozonation disinfect but do not remove nitrates, and sedimentation only removes solids.
Which greenhouse gas has the highest global warming potential over a 100-year horizon?
Carbon dioxide (CO2)
Methane (CH4)
Nitrous oxide (N2O)
Sulfur hexafluoride (SF6)
Sulfur hexafluoride has a GWP around 23,500 over 100 years, far exceeding COâ‚‚, CHâ‚„, and Nâ‚‚O. It is used in electrical insulation but is a potent greenhouse gas.
A machine produces 500 kWh of useful energy from 1000 kWh of input energy. What is its efficiency?
100%
200%
5%
50%
Efficiency is output divided by input: 500/1000 = 0.5 or 50%. It measures how well the machine converts input into useful work.
Under ISO 14001, what is the main requirement for continuous environmental improvement?
Mandatory incineration of all waste
Establishment of an environmental management system using the PDCA cycle
Annual financial profit reporting
Fixed emission limits only without review
ISO 14001 requires organizations to implement a Plan-Do-Check-Act (PDCA) cycle for continuous environmental improvement. Other answers do not reflect its systematic management approach.
In selecting materials for a new product, increasing durability often leads to which trade-off?
Increased biodegradability
Reduced recyclability due to complex composites
Decreased strength under load
Lower cost in all cases
Highly durable materials often use composite formulations that complicate end-of-life recycling. Durable design does not usually increase biodegradability or universally lower costs.
Option A emits 5 units of CO2 and 3 units of NOx, while Option B emits 2 units of CO2 and 8 units of NOx. If both gases are weighted equally, which option has the lower environmental impact?
Insufficient data to decide
They have equal impact
Option B
Option A
Weighted impact for A is (5 + 3) / 2 = 4 units, and for B is (2 + 8) / 2 = 5 units. Option A has the lower average impact.
In error propagation for independent measurements, if each has a relative uncertainty of ±2%, what is the combined uncertainty when the measurements are multiplied?
±1%
±0.25%
±4%
±2.8%
For independent errors, relative uncertainties combine by the square root of the sum of squares: √(2² + 2²) ≈ 2.8%. Simply adding errors would overestimate the uncertainty.
A solar array produces 200 W/m² at peak and receives 5 peak sun hours per day. What area is needed to generate 1 MWh in a single day?
500 m²
2000 m²
1000 m²
250 m²
Daily energy per m² is 200 W à - 5 h = 1000 Wh = 1 kWh. To get 1000 kWh (1 MWh), you need 1000 m² of panels at that rate.
