Q1.Anaerobically treated effluent has MPN of total coliform as 106 / mL. After
chlorination, the MPN value declines to 102 / mL. The percent removal (%R) and log removal (logR) of total coliform MPN is
Answer : Option DExplaination / Solution: No Explaination.
Q2.Consider the following unit processes commonly used in water treatment; rapid mixing (RM), flocculation (F), primary sedimentation (PS), secondary sedimentation (SS), chlorination (C) and rapid sand filtration (RSF). The order of these unit processes (first to last) in a conventional water treatment plant is
Answer : Option DExplaination / Solution: No Explaination.
Q4.A 16 mm thick plate measuring 650mm X 420 mm is used as a base plate for an ISHB 300 column subjected to a factored axial compressive load of 2000 kN. As per IS 456-2000, the minimum grade of concrete that should be used below the base plate for safely carrying the load is
Answer : Option AExplaination / Solution: No Explaination.
Q5.Consider a reinforcing bar embedded in concrete. In a marine environment this bar undergoes uniform corrosion, which leads to the deposition of corrosion products on its surface and an increase in the apparent volume of the bar. This subjects the surrounding concrete to expansive pressure. As a result, corrosion induced cracks appear at the surface of concrete. Which of the following statements is TRUE?
Answer : Option CExplaination / Solution: No Explaination.
Q7.Choose the most appropriate word from the options given below to complete the

If you are trying to make a strong impression on your audience, you cannot do
so by being understated, tentative or _________.
Answer : Option BExplaination / Solution: No Explaination.
Q8.Consider a simply supported beam with a uniformly distributed load having a neutral axis (NA) as shown. For points P (on the neutral axis) and Q (at the bottom of the beam) the state of stress is best represented by which of the following pairs?
Answer : Option AExplaination / Solution: No Explaination.
Q9.Choose the most appropriate word(s) from the options given below to complete
the following sentence.
I contemplated ________ Singapore for my vacation but decided against it.
Answer : Option CExplaination / Solution: No Explaination.
Q10.A field vane shear testing instrument (shown alongside) was inserted completely
into a deposit of soft, saturated silty clay with the vane rod vertical such that the
top of the blades were 500 mm below the ground surface. Upon application of a
rapidly increasing torque about the vane rod, the soil was found to fail when the
torque reached 4 6. Nm. Assuming mobilization of undrained shear strength on
all failure surfaces to be uniform and the resistance mobilized on the surface of
the vane rod to be neglibible, what would be the peak undrained shear strength
(rounded off to the nearest integer value of kPa) of the soil?
Answer : Option BExplaination / Solution: No Explaination.
