Identify the correct relationship with respect to water quality from the following options.
Identify the correct relationship with respect to water quality from the following options.
Show Hint
Always distinguish between suspended solids, dissolved solids, and colloidal solids when calculating water quality parameters.
Updated On: Jan 13, 2026
- Total solids = Suspended solids + Dissolved solids + Colloidal solids
- Total gases = Biological Oxygen Demand + Chemical Oxygen Demand + Dissolved Oxygen
- Total solids = Suspended Solids + Dissolved solids
- Total gases = Biological Oxygen Demand + Chemical Oxygen Demand
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Total solids in water encompass all material present, comprising both suspended and dissolved components. Suspended solids are insoluble, visible particles. Dissolved solids are substances like salts and minerals that have dissolved in water.
Step 2: Colloidal solids are minuscule particles that remain suspended and do not readily settle. They are typically excluded from total solids calculations. Consequently, the accurate relationship omits colloidal solids.
Step 3: The calculation for total solids is defined as: \[{Total solids} = {Suspended solids} + {Dissolved solids}.\] Conclusion: Total solids are accurately represented as the aggregate of suspended solids and dissolved solids.
Step 2: Colloidal solids are minuscule particles that remain suspended and do not readily settle. They are typically excluded from total solids calculations. Consequently, the accurate relationship omits colloidal solids.
Step 3: The calculation for total solids is defined as: \[{Total solids} = {Suspended solids} + {Dissolved solids}.\] Conclusion: Total solids are accurately represented as the aggregate of suspended solids and dissolved solids.

- A real estate project on a 12 hectare site contains 6 buildings, each with ground coverage of 3 percent of the site area. The landscaped area is 40 percent of the site and rest of the area are roads. Assume coefficient of runoff for landscaped area and road area to be 0.15 and 0.6 respectively. Ignore the rainwater from the roof of the buildings and additional water from outside areas. Considering average rainfall intensity of 70 mm per hour, the estimated peak surface runoff rate from the site is ________ \(m^{3}\)/s. (rounded off to two decimal places)
