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)

A city has a population of 1,75,000. Using the Kuichling’s formula the estimated fire demand for the city is _________ litres/min. (rounded off to two decimal places)

A declining Industrial Town has proposed to improve water sustainability by reducing stormwater runoff through change of land use land cover (LULC), as shown in the Table below, to attract new residents.

LULC	Runoff Coefficient	Existing Area in hectare	Proposed Area in hectare
Industrial	0.7	1500	800
Residential	0.5	1000	1200
Park and Playgrounds	0.25	1200	1000
Forest	0.15	300	1000

Considering a flat topography and zero additional runoff from the adjoining areas, the reduction in run-off generation for a 400 mm rainfall event in the industrial town for the proposed intervention, in cubic meters, is  _____ \(\times  10^6\)  (rounded off to two decimal places).

The design of a 1200 capacity concert hall considers 1/3rd female audience and 2/3rd male audience. The Table below shows the guideline for calculating Water Closet requirements.

Fixture	Male	Female
Water closet	1 number per 100 up to 400 and over 400, 1 number for every 250 or part thereof	3 numbers per 100 up to 200 population and over 200, 2 numbers for every 100 or part thereof

Using the above guideline, the number of Water Closets required for the total audience is _______(in integer).

Which of the following is/are component(s) of Right of Way (RoW) of a road?

A municipal town requires a volume of 70,000 \(m^3\) compacted solid waste to fill a low lying land. The city has a total of 10,000 households.

Type of House	Percentage of Households	Equivalent volume of compacted solid waste generated/ household/ day
LIG	30%	0.10 \(m^3\)
MIG	60%	0.15 \(m^3\)
HIG	10%	0.20 \(m^3\)

Using the information as shown in the Table above, the estimated minimum number of days required to fill the low lying land is _______ (in integer).
