What percentage of overall consumption is made up of water lost due to waste and theft?
15% of overall consumption is made up of water lost through thefts and waste, which includes water lost through leaks or stolen through unauthorized connections.
Which unit process transforms unwanted solutes into acceptable forms without removing them?
To change unwanted solutes into acceptable forms, water is stabilized by liming or chlorination during the solute stabilization process.
The vertical flow clarifier's detention time is .
The vertical flow clarifier's typical design value for the detention duration is between 1 to 1.5 hours. Usually, they take the flocculent out.
What is the formula for the arithmetical rise approach of population forecasting?
The arithmetical increase method's equation is given by PO+n*x, where PO stands for the current population, x for the average rate of population growth over a known decade, and n for the number of decades.
A rectangular tank's detention time is determined by .
A rectangular tank's detention period is calculated using the formula t0 = LBH/Q, where L is the tank's length, B is its breadth, H is its height, and Q is its discharge rate.
Which population forecasting approach assumes a constant percentage increase in population from decade to decade?
The geometrical increase method assumes a constant percentage population growth from decade to decade. From a population of three or four decades, the population's percentage rise is calculated, and its average is then calculated.
The primary stress is 1 when in a quiescent state.
The minor primary stress in passive mode, indicated by the symbol 3, is directed vertically. The primary principal stress in the passive state, 1, is horizontal in nature.
The minor primary stress 3 in the active state is .
The minor primary stress in the active state, indicated by the symbol 3, is oriented horizontally. The minor primary stress 3 is vertical while the system is in the passive condition.
When failure is imminent, the plastic state of stress was studied by .
In the year 1860, Rankine investigated the plastic condition of stress failure in soil samples. For his contributions to the study of soil permeability, Darcy is well known.
The backfill's top surface is present.
Both a horizontal and an inclined top surface are possible for the backfill. It should be emphasized that the angle must not be greater than the angle at which the soil is in repose in order for it to work.
__________ is utilized in maintaining the ground surface at different elevations.
The backfill soil's lateral earth pressure is resisted by the retaining wall. By preserving the ground surface at various altitudes in hilly areas, it prevents landslides.
Fire hydrants must have a minimum water pressure of 100-150 kN/m2, or 10-15 m of water head, and it must be maintained for four to five hours. When the pH of the water is between ____, alum is effective.
When the pH of the water is between 6.5 and 8.5, alum is effective. Its dosage is influenced by the water's turbidity, color, taste, pH, and temperature.
Which of the following structures is statically determined?
There are three equilibrium equations that can be used to analyze double overhanging: ∑Fx=0, ∑Fy=0, and ∑M = 0.2
Which one of the subsequent structural loads is not frequently applied to a building?
To buildings, three sorts of loads are always applied.
The retaining wall's substance is referred to as .
Backfill is the term for the material the retaining wall holds. The backfill's surface might be either horizontal or angled. It should be noted that the angle is within the soil's angle of repose.
What is the maximum permissible decrease percent in the case of a structural member supporting more than one level with a load above 100psf?
Studies have revealed that a floor is rarely loaded with more than 80% of its design load in structures with more than one storey.
