Q1.Water(γw = 9.879 kN/m3) flows with a flow rate of 0.3 m3 sec through a pipe AB
of 10 m length and of uniform cross-section. The end B is above end A and the
pipe makes an angle of 30o to the horizontal. For a pressure of 12 N/m2 at the
end B, the corresponding pressure at the end A is
Answer : Option DExplaination / Solution: No Explaination.
Q3.The depth of flow in a alluvial channel is 1.5 m If critical velocity ratio is 1.1 and
Manning’s n is 0.018, the critical velocity of the channel as per Kenedy’s method
is
Answer : Option BExplaination / Solution: No Explaination.
Q4.An agricultural land of 437 ha is to be irrigated for a particular crop. The base
period of the crop is 90 days and the total depth of water required by the crop is
105 cm. If a rainfall of 15 cm occurs during the base period, the duty of irrigation
water is
Answer : Option DExplaination / Solution: No Explaination.
Q5.One hour triangular unit hydrograph of a watershed has the peak discharge of 60 m3 /sec cm at 10 hours and time base of 30 hours. The Φ index is 0.4 cm per hour and base flow is 15 m3 /sec.
If there is rainfall of 5.4 cm in 1 hour, the ordinate of the flood hydrograph at
15th hour is
Answer : Option BExplaination / Solution: No Explaination.
Q9.A water treatment plant is required to process 28800 m3 /d of raw water
(density=1000 kg/m3, kinematic viscosity = 10-6 m2/s). The rapid mixing tank
imparts a velocity gradient of 900s-1 to blend 35 mg/L of alum with the flow for
a detention time of 2 minutes. The power input (W) required for rapid mixing is
Answer : Option DExplaination / Solution: No Explaination.
Q10.A person standing on the bank of a canal drops a stone on the water surface. He
notices that the disturbance on the water surface is not travelling upstream. This
is because the flow in the canal is
