For the following questions answer them individually
The diameter at the inlet end of a tapered pipe is halved at the outlet end. If the flow velocity of an incompressible fluid at the inlet end is given as V. then the flow velocity at the outlet end should be ____________
A sluice gate 3m wide and 2m deep s placed in water such that the top of edge of the gate is 3m below the free surface of water. The depth of pressure will be located at ______________ below the free surface of water.
The diameter of a pipe is suddenly doubled. If the velocity of flow of water before enlargement is 2 m/s. then the headloss due to this sudden enlargement will be _____________
A nearly hemispherical boulder of radius 1 m is lying on the bed of a canal as shown in the following figure. If the depth of water in the canal is 4m. then the vertical component of hydrostatic force on the boulder will be about ________________

A 20 mm dia pipe carries water at a velocity of 2.5 m/s. If the value of Reynolds number is given as 1280, then the head loss per kilometre through the pipe should be about ______________
Two pipes such that the diameter of one is twice that of the other are used to carry water from one tank to another. Given the conditions that both the pipes have the same value of f, both tanks have different water surface elevation and minor losses being negligible the ratio of rate of flow through the two pipes should be equal to _____________

Choose the correct answer from the options given below :
Given below are two statements:
Statement I : In an initially dry soil. the infiltration rate is low at the beginning of the rain or irrigation.
Statement II : The basic infiltration rate of a soil is approximately equal to the permeability of saturated soil.
In the light of the above statements. choose the most appropriate answer from the options given below:
Given below are two statements:
Statement I : The sum of the specific yield and specific retention would be equal to the porosity of the given soil formation.
Statement II : The product of the average specific yield of a saturated water bearing formation and its total volume gives the volume of water which can be recovered from the formation by gravity drainage.
In the light of the above statements. choose the most appropriate answer from the options given below:
