The distance between successive vehicles moving in the same line
measured from head at any instance is
(a) the space headway
(b) the time headway
(c) the one-way stream
(d) the head-way stream
(A)
The roads which are provided with a hard pavement course having at
least a water bound macadam (WBM) layer are classified as
(a) Paved roads
(b) Unpaved roads
(c) Surface roads
(d) Unsurfaced
roads
(A)

A cipolletti weir has length of 2.0 m and head over the weir is 1
m. What is the discharge
over the weir? (Take Cd = 0.62)
(a) 10.35 m3/s
(b) 3.66 m3/s
(c) 45.21 m3/s
(d) 75.68 m3/s
(B)
Q = 2 /3 Cd (2g)1/2 H3\2
Which one of the following is an advantage using a triangular notch
over a rectangular notch?
(a) Ventilation of a triangular notch is necessary
(b) The same triangular notch cannot measure a wide range of
flows accurately
(c) For heavy discharges, a triangular notch gives more accurate
results than a rectangular
notch.
(d) In a given triangular notch, only one reading is required to
be taken for the measurement
of discharge
(D)
A triangular notch is preferred to a rectangular notch due to following reasons:
1. The expression for discharge for a right angled V-notch is very simple.
2. For measuring low discharge, a triangular notch gives more accurate results than
a rectangular notch.
3. In case of triangular notch, only one reading, i.e., H is required for the computation
of discharge.
4. Ventilation of triangular notch is not necessary.
