FAQs on Quality Parameters of Water Video Lecture - Environmental Engineering - Civil Engineering (CE)

1. What are the main quality parameters of water in civil engineering?
Ans. The main quality parameters of water in civil engineering include physical parameters such as temperature, color, turbidity, and odor, as well as chemical parameters such as pH, dissolved oxygen, total dissolved solids (TDS), hardness, alkalinity, and presence of contaminants like heavy metals and organic compounds.
2. How is water temperature measured in civil engineering?
Ans. Water temperature in civil engineering is typically measured using a thermometer. The thermometer is inserted into the water body, and the temperature reading is recorded. It is important to measure water temperature as it affects various aspects of civil engineering projects, such as the design of water supply systems and the behavior of concrete structures.
3. What is turbidity and how is it measured in water?
Ans. Turbidity refers to the cloudiness or haziness of water caused by suspended particles. It is an important parameter in civil engineering as high turbidity can affect the efficiency of water treatment processes and the performance of hydraulic structures. Turbidity is measured using a turbidimeter, which passes light through the water sample and measures the scattering of light caused by the suspended particles. The measurement is usually expressed in nephelometric turbidity units (NTU).
4. Why is the pH of water important in civil engineering?
Ans. The pH of water is important in civil engineering as it affects the performance and durability of various materials and structures. For example, acidic water can corrode metal pipes, whereas alkaline water can lead to scaling in water supply systems. pH is measured using a pH meter, which provides a numerical value indicating the acidity or alkalinity of the water. The desired pH range for different civil engineering applications varies depending on the materials and processes involved.
5. What are total dissolved solids (TDS) and why are they significant in civil engineering?
Ans. Total dissolved solids (TDS) refer to the combined content of inorganic salts, organic matter, and other dissolved substances in water. TDS is an important parameter in civil engineering as it can affect the quality of water for various purposes, including drinking water, irrigation, and construction. High TDS levels can lead to water hardness, scaling, and reduced effectiveness of water treatment processes. TDS is typically measured using a conductivity meter, which measures the electrical conductivity of water and correlates it with the TDS concentration.
