Q7. Identical surcharges are placed at ground surface at sites X and Y , with soil conditions shown alongside and water table at ground surface. The silty clay layers at X and Y are identical. The thin sand layer at Y is continuous and freedraining with a very large discharge capacity. If primary consolidation at X is estimated to complete in 36 months, what would be the corresponding time for completion of primary consolidation at Y ?

No Explaination.


Q8. Total suspended particulate matter (TSP) concentration in ambient air is to be measured using a high volume sampler. The filter used for this purpose had an initial dry weight of 9.787g. The filter was mounted in the sampler and the initial air flow rate through the filter was set at 1.5min/m3. Sampling continued for 24 hours. The airflow after 24 hours was measured to be 1.4 min/m3. The dry weight of the filter paper after 24 hour sampling was 10.283g. Assuming a linear decline in the air flow rate during sampling, what is the 24 hour average TSP concentration in the ambient air?
Answer : Option C
Explaination / Solution:
No Explaination.


Q9. Chlorine gas (8 mg/L as Cl2) was added to a drinking water sample. If the free chlorine residual and pH was measured to be 2 mg/L (as Cl2) and 7.5, respectively, what is the concentration of residual OCl- ions in the water? Assume that the chlorine gas added to the water is completely converted to HOCl and OCl-. Atomic Weight of Cl: 35.5

Answer : Option B
Explaination / Solution:
No Explaination.


Q10. The ordinates of a 2-h unit hydrograph at 1 hour intervals starting from time t = 0, are 0, 3, 8, 6, 3, 2 and 0 m3/s. Use trapezoidal rule for numerical integration, if required.
