The performance of a border irrigation event was evaluated by taking soil moisture measurements at 12 locations along the border from the upstream end. The computed irrigation depths at those locations were 50, 49, 48, 47, 46, 45, 44, 43, 42, 41, 40, and 39 mm. The Christiansen Uniformity Coefficient (CU) for the event, in %, is _______. (Rounded off to 2 decimal places)

Ques 54 GATE 2024

A flow rate of 2 m³.s⁻¹ is to be carried out in an open channel at a velocity of 1 m.s⁻¹. The cross section of the channel is rectangular with depth equal to one-half of the width. Considering Manning's roughness coefficient (n) as 0.02, the slope of the channel, in %, is _______. (Rounded off to 2 decimal places)

Ques 55 GATE 2024

In an area, one tubewell of 15 cm diameter was operating such that groundwater table is 40 m above the bottom of screen. The groundwater formation has permeability (K) as 20 m.d⁻¹ and well has radius of influence of 980 m with a maximum drawdown of 12 m. After some time, a second tubewell of same size was installed at a distance of 500 m from the first tubewell. If both the tubewells are running simultaneously and have equal discharge, the loss of discharge in the first tubewell due to installation of the second tubewell, in %, is _______. (Rounded off to 2 decimal places)

Ques 56 GATE 2024

A single acting reciprocating pump, running at 40 rpm, has piston of 20 cm diameter and stroke length of 40 cm. The suction and delivery heads are 5 m and 20 m, respectively. Assuming overall pump efficiency as 80%, the power requirement of the pump, in kW, is _______. (Rounded off to 2 decimal places)

A soil sample of diameter 70 mm was used for constant head permeability test. The observed head loss was 80 mm in the soil sample length of 100 mm and water collected in one minute was 60 mL. The coefficient of permeability, in mm.s⁻¹, is _______. (Rounded off to 2 decimal places)

Ques 65 GATE 2024

A surveyor started a longitudinal section leveling survey by taking starting bench mark of elevation 53.85 m. During the survey, he takes an observation of intermediate sight of 2.42 m with the staff held on another bench mark of 85.45 m. The sum of the back sights from the start to the point is 50.28 m and that of fore sight is 16.30 m. If the surveyor ends the survey operation on the second bench mark, the error of closure on the second bench mark, in m, is _______. (Rounded off to 2 decimal places)
