The sudden stoppage in flow of water in a closed conduit results in a phenomenon is called

Cavitation

Cavitation is a phenomenon in which rapid changes of pressure in a liquid lead to the formation of small vapor-filled cavities, in places where the pressure is relatively low. When subjected to higher pressure, these cavities, called "bubbles" or "voids", collapse and can generate an intense shock wave.

Hydraulic gradient
The Hydraulic Gradient is a vector gradient between two or more hydraulic head measurements over the length of the flow path.

Stack effect

Stack effect or chimney effect is the movement of air into and out of buildings, chimneys, flue-gas stacks, or other containers, resulting from air buoyancy. Buoyancy occurs due to a difference in indoor-to-outdoor air density resulting from temperature and moisture differences.

Answer 12 - 

Increase in volume of fine aggregates due to the presence of moisture is called
The increase in moisture of sand increases the volume of sand. The reason is that moisture causes film of water around sand particles which results in the increase of volume of sand. For a moisture content percentage of 5 to 8 there will be an increase in volume up to 20 to 40 percent depending upon sand. If the sand is more fine there will be more increase in volume. This is known as bulking of sand.

Answer 42 -
Population = 50000
household size = 5.0
occupied dwelling unit = 8400

in dilapidated condition = 8400 x 10/100 = 840 

housing demand = ?

solution
dwelling units at current = occupied - dilapidated = 8400-840=7560

required dwelling units = population / household size
                                      =  50000/5 = 10000

Housing demand = required dwelling - dwelling at current
                            =  10000 - 7560
                            =  2440

Answer 48 -

Roof top area =  300 sq.ft

rainfall  =  700 mm

runoff coefficient  = 0.8 (rooftop)

Max. amount of rainfall

= runoff coefficient x rainfall intensity x area

= 300 sq.m  x 0.8 x 700 mm

= 300 sq.m  x 0.8  x .7 m

=  168 cu.m

= 168 x 1000  ltr.

= 168000 ltr.

Answer 53 -
Volume = 2000 cu.m   (v)
total absorption = 80 sq.m sabines     (s)

• Reverberation time = 0.161 V / S

                               = 0.161 x 2000 / 80
                               = 4 sec

Answer 54 -
Reverberation time = 2.0 s

•  total absorption = 0.161 V / RT

                                 = 0.161 x 2000 / 2
                                 = 161 sq.m sabines
