Identify the correct relationship with respect to water quality from the following options.
Show Hint
- 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
The Correct Option is C
Solution and Explanation
\n\nStep 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.
\n\nStep 3: The calculation for total solids is defined as: \n\[\n{Total solids} = {Suspended solids} + {Dissolved solids}.\n\] \n\nConclusion: 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)

An individual chooses a transport mode for a particular trip based on three attributes i.e., cost of journey (X), In-vehicle travel time to reach destination (Y), and Out-of-vehicle time taken to access mode at respective stops (Z). The values for these attributes for three modes Rail, Bus and Para-transit are given in the table. If the general utility (U) equation is \( U = - 0.5 \times X - 0.3 \times Y - 0.4 \times Z \), using the Logit model, the estimated probability of choosing Bus is _________ (rounded off to two decimal places).
