Ques 1 GATE 2013
Maximum possible value of Compacting Factor for fresh (green) concrete is:
Ques 2 GATE 2013
Some of the water quality parameters are measured by titrating a water sample with a titrant. Group-I gives a list of parameters and Group-II gives the list of titrants. The correct match of water quality parameters in Group-I with titrants in Group-II is:
Ques 3 GATE 2013
A water treatment plant is designed to treat 1 m3/s of raw water. It has 14 sand filters. Surface area of each filter is 50 m2. What is the loading rate (in m3/(day x m2)) with two filters out of service for routine backwashing?
Ques 4 GATE 2013
A settling tank in a water treatment plant is designed for a surface overflow rate of 30 m3/(day x m2). Assume specific gravity of sediment particles = 2.65, density of water (ρ) = 1000 kg/m3, dynamic viscosity of water (μ) = 0.001 N x s/m2, and Stokes' law is valid. The approximate minimum size of particles that would be completely removed is:
Ques 5 GATE 2013
A student began an experiment for determination of 5-day, 20°C BOD on Monday. Since the 5th day fell on Saturday, the final DO readings were taken on the next Monday. On calculation, BOD (i.e., 7-day, 20°C) was found to be 150 mg/L. What would be the 5-day, 20°C BOD (in mg/L)? Assume the value of BOD rate constant (k) at the standard temperature of 20°C as 0.23/day (base e).
Ques 6 GATE 2013
Elevation and temperature data for a place are tabulated below: Based on the above data, the lapse rate can be referred to as:

Ques 8 GATE 2013
Group-I contains dimensionless parameters and Group-II contains the ratios. The correct match of dimensionless parameters in Group-I with ratios in Group-II is:
Ques 9 GATE 2013
For a two dimensional flow field, the stream function is given as \(\psi = \frac{3}{2}(y^2 - x^2)\). The magnitude of discharge occurring between the stream lines passing through points (0,3) and (3,4) is:
Ques 10 GATE 2013
A 2 km long pipe of 0.2 m diameter connects two reservoirs. The difference between water levels in the reservoirs is 8 m. The Darcy-Weisbach friction factor of the pipe is 0.04. Accounting for frictional, entry and exit losses, the velocity in the pipe (in m/s) is:
Ques 11 GATE 2013
The normal depth in a wide rectangular channel is increased by 10%. The percentage increase in the discharge in the channel is:
