(a) 1 : 500
(b) 1 : 1000
(c) 1 : 2500
(d) 1 : 50,000

(a) TOD > BOD > COD
(b) BOD > COD > TOD
(c) COD > BOD > TOD
(d) TOD > COD > BOD
Q4. Which of the following is the correct sequence of the parts of a canal system?
(a) Head works, distributary and minor
(b) Head works, main canal and minor
(c) Head works, main canal, branch canal, distributary and minor
(d) None of the above
Q5. Minimum pitch of the rivets shall not be less than:
Q6. The ratio between adopted centrifugal ratios for roads and railways is
(a) 3 : 1
(b) 2 : 1
(c) 5 : 1
(d) 4 : 1
Sol. Arrangement of scale from largest to smallest.
Hence, 1∶500 is the largest scale.
Sol. The strength of cement decreases after storage.
|Time||Reduction in strength|
Sol. The correct relationship between TOD, COD and BOD is
Sol. Correct sequence of the parts of a canal system is
Head works → main canal → Branch canal → Distributary → Minor.
Sol. Minimum pitch of rivets should be 2.5 times the nominal diameter or rivet i.e. 2.5d.
d = nominal diameter of rivet.
→ Maximum value of centrifugal ratio for roads = 1/4
→ Maximum value of centrifugal ratio for railways = 1/8
So, ratio between these two = (1/4)/(1/8)
= (2 : 1)
