- A neighbourhood with a total area of 200 hectares has a gross density of 300 persons per hectare (pph). If the residential area is 60% of the total area, then net density (in pph) of the neigh bourhood is

View Hint View Answer Discuss in Forum
Gross density = 300 ppha
If residential area is 60% of the total area.
Then net density = 300/0.6 = 500 pphaCorrect Option: C
Gross density = 300 ppha
If residential area is 60% of the total area.
Then net density = 300/0.6 = 500 ppha

- A site has 6 contour lines and the length of the line joining the midpoints of the highest contour and lowest contour is 300m. If the slope of the line is 1 in 10, then the contour interval (in m) is
-

Run = 300m
Slope = 1/10
So, rise or drop = 30 m
Number of Contour lines = 6
Number of contour intervals = 5
Therefore contour interval = 30/5 = 6 mCorrect Option: B
Run = 300m
Slope = 1/10
So, rise or drop = 30 m
Number of Contour lines = 6
Number of contour intervals = 5
Therefore contour interval = 30/5 = 6 m

The below mentioned terminologies are used to express different forms of cut bricks used in brick masonry construction.
1. CLOSER
It is the portion of the brick cut along the length in such a way as one long face remains intact.
2. QUEEN CLOSER
When a brick is cut along its length, making it two equal halves then it is called queen closer. Thus a queen closer is a broken brick portion whose width is half as wide as the original brick. This is also called as queen closer half.
3. QUEEN CLOSER QUARTER
If a queen closer is broken into two equal pieces then it is known as queen closer quarter. Such a closer is thus a brick piece which is one quarter of the brick size.
Different forms of Queen closer
4. KING CLOSER
If a brick is cut in such a way that the width of one end becomes half that of a full brick, while the width at the other end is equal to the full width, then it is called as king closer. It is obtained by cutting out a triangular portion of the brick between the centre of one end (width side) and the centre of the other end (lay side). Thus it has half header and half stretcher face.
5. BEVELED CLOSER
It is a form of king closer in which the whole length of the brick (i .e. st r et cher face) is chamfered or beveled in such a way that half width is maint ained at one end and full widt h is maintained at the other end.
6. MITRED CLOSER
It is a portion of a brick whose one end is cut splayed or mitred for full width. The angle of splay may vary from 45° to 60°. Thus one longer face of the mitred closer is of full length of the brick while the other longer face is smaller in length.
King closer - Beveled closer - Mitred closer
7. BAT
When a brick is cut across the width, the resulting piece is called bat. Thus a bat is smaller in length than the full brick.
8. HALF BAT
If the length of the bat is equal to half the length of the original brick, it is known as half bat.
9. THREE QUARTER BAT
It is a form of brick bat having its length equal to three quarter of the length of a full brick.
10. BEVELED BAT
A brick bat is called beveled bat, when its width has beveled.
