Test: Water Resources Engineering - 6 - Civil Engineering (CE) MCQ

The run off is affected by

The form factor of a drainage basin is obtained by dividing

Pick up the correct statement from the following :

Pressure exerted by fully saturated air, is known

A volume of air at constant barometric pressure may be brought to dew point by

If the dew point is greater than 0�C

Humidity refers to

The formula for calculating the overland flow time (T_o) in hours for any basin, is (where L_o is the distance of the critical point and H is the difference in elevation)

Pick up the correct statement from the following :

Bernard's distribution graph is a plot of time on X-axis and

An intense rain is falling at a uniform rate of 7.5 cm/hour for a period of 60 minutes on a basin whose areas is 500 hectares. If the average infiltration capacity during the entire rain period is assumed to be 1.5 cm/hr, the maximum run-off rate based on 10 minute peak percentage of 16% from distributing graph of the basin, is

Pick up the correct statement from the following :

Isopiastic lines are the contours

The coefficients of permeability of soils of an unconfined aquifer and another confined aquifer were determined by pumping water from the wells and observing the effect of water table in two test wells at equal distances was found to be equal. The total height of confined aquifer H is given by

The radius of influence is

When a constant discharge 2.91 litres/sec. was obtained in a pumping test, the draw downs in the test wells at 3 m and 6.184 m were 2.6 m and 0.3 m respectively. If over-all depth of the pumping well was 16 m, the permeability of the soil, is

If ω is unit weight of water, Q the discharge in cumecs, H the total head lift and η, the efficiency of the pump, the H.P. of the motor is

If h is the loss due to friction in a pipe. Total losses in strainer and bends may be taken as

If the loss due to friction in pipes is 4 m, the total losses in strainer and bends may be taken as

The rate of evaporation from reservoirs may be determined by

Dicken's formula for high flood estimate, is useful only for the catchments in

In estimating the rate of evaporation from the reservoir surface, a pan 1.5 metres in diameter, was filled upto 8.0 cm. During a specified period of time, the rainfall recorded was 5 cm. 3 cm of water was removed from the pan to keep the depth of water. At the end of the time, the depth was 9 cm. If the pan coefficient is 0.6, the evaporation loss is
