Test: Water Demand - Question 1

Which one of the following practices, causes reduction in the per capita water consumption?

Detailed Solution for Test: Water Demand - Question 1

Good Quality water, hotter climate and modern living, all these factors will increase the per capita water consumption.
However, metering system will reduce the consumption as people will be cautious while using the water as they need to pay for it.

Test: Water Demand - Question 2

The multiplying factor, as applied to obtain the maximum daily water demand, in relation to the average i.e. per capita daily demand, is

Detailed Solution for Test: Water Demand - Question 2

Maximum daily demand
= 1.8 x Average daily demand Maximum hourly demand
= 1.5 x Maximum daily demand

Test: Water Demand - Question 3

If the average daily water consumption of a city is 24000 cum, the peak hourly demand (of the maximum day) will be

Detailed Solution for Test: Water Demand - Question 3

Maximum hourly consumption of the maximum day i.e. peak demand

Test: Water Demand - Question 4

The total water requirement of a city is generally assessed on the basis of

Detailed Solution for Test: Water Demand - Question 4

For general community purposes, the total draft is not taken as the sum of maximum hourly demand and fire demand, but is taken as the sum of maximum daily demand and fire demand, or the maximum hourly demand, whichever is more. The maximum daily demand (i.e. 1.8 times the average daily demand) when added to fire draft,for working out total draft, is known as coincident draft.

Test: Water Demand - Question 5

As compared to the geometrical increase method of forecasting population, the arithmetical increase method gives.

Detailed Solution for Test: Water Demand - Question 5

In geometric increase method compounding is done every decade unlike in arithmetic increase method. Thus geometrical increase method gives higher value than the arithmetic increase method.

Test: Water Demand - Question 6

The growth of population can be conveniently represented by a curve, which is amenable to mathematical solution, The type of this curve is 

Detailed Solution for Test: Water Demand - Question 6

Equation of logistic curve is given by,
In [(Ps - P)/(Ps - P0)] = -kPst
where,
P0 = The population at the start pt. of the curve A
Ps = Saturation population
P = Population at any time t from the origin A
K = Constant

The population figures in a growing town are as follows:

The predicted population in 2010 by Arithmetic Regression method is

Detailed Solution for Test: Water Demand - Question 9


∴ Design growth rate,

In 2010 population will be,
P = 58000 + 6000 = 64000

Test: Water Demand - Question 10

The pipe mains carrying water from the source to the reservoir are designed for the

Detailed Solution for Test: Water Demand - Question 10

The pipe mains carrying water from the source to the reservoir are designed for the maximum daily draft = 1.8 times the average daily draft.
However, pipes for distributing water to households etc. are designed for maximum hourly draft of the maximum day = 2.7 times the average daily draft.
