(a) 9,00,000

(b) Safe bearing capacity
(c) Tangent modulus
(d) Modulus of subgrade reaction

Q4. In slow sand filters, the rate filtration is –
(a) 100 to 200 litres/ hours per. sq. m. of filter area
(b) 200 to 300 litres/ hour per. sq. m. of filter area
(c) 100 to 200 litres/ hour per. sq. m. of filter area
(d) 200 to 300 litres/ hour per. sq. m. of filter area

Q5. The average value of co-efficient of velocity is
(a) 0.84
(b) 0.76
(c) 0.97
(d) 0.62

Q6. For slabs spanning in two directions the ratio of span to depth should not exceed:
(a) 15
(b) 25
(c) 35
(d) 50

Solutions

S1. Ans.(d)
Sol. Plastering is measured in terms of m². If,
(a) opening area < 0.5 m² (No deduction is applied)
(b) opening area is between 0.5 m² – 3m², then (single side deduction is applied)
(c) opening area > 3 m², then (double side deduction is applied)

S2. Ans.(c)
Sol. Given, rate of interest (i) = 5%
Annual rent = 1,80,000 Rs.
Capitalized value =?
Year’s purchase = 100/(i%)=100/5=20 years
Capitalized value of building = Annual rent × year’s purchase
= 1,80,000 × 20
= 36,00,000 Rs

S3. Ans.(d)
Sol. The pressure sustained per unit deformation of subgrade at specified deformation level using specified plate size is termed as modulus of subgrade reaction.
▭(Moduius of subgrade reaction (K)=(pressure (P))/(Deflection (D)))
(unit = kg/m³)
It is generally calculated at 0.125 cm or 1.25 mm.

S4. Ans.(a)
Sol. The rate of filtration for slow sand filters is 2400 to 4800 l/day/m² or 100 to 200 l/hour/m².

S5. Ans. (c)
Sol. Velocity (V₁) = C_v √2gh
C_v ⇒ coefficient of velocity
C_v ⇒ 0.97 – 0.99

S6. Ans.(c)
Sol. Slabs spanning in one direction (one way slab)
l/d=30
Slabs spanning in two directions (two-way slab)
l/d<35 (simply supported)
l/d≤40 (continous)
