सही: ० / ०
-
A canal aligned along the watershed (ridge line) of an area has the main advantage that:
सही उत्तर: क) Cross-drainage works are largely avoided
Natural drains originate on either side of the ridge, so a ridge canal seldom crosses them.

A venturimeter is used to measure:
सही उत्तर: ख) Discharge through a pipe
A venturimeter measures pipe discharge from the pressure difference between inlet and throat.

According to Bligh's creep theory, the minimum creep length required for a weir with a head of 4 m and Bligh's creep coefficient 12 is:
सही उत्तर: घ) 48 m
L = C × H = 12 × 4 = 48 m.

Lines joining points of equal rainfall on a map are called:
सही उत्तर: क) Isohyets
Isohyets are lines of equal rainfall depth.

-
In a hydropower scheme, a surge tank is provided mainly to:
सही उत्तर: ग) Protect the penstock from water hammer pressure
A surge tank absorbs pressure rise from sudden load rejection and reduces water hammer in the penstock.

The Darcy–Weisbach equation for head loss due to friction in a pipe is:
सही उत्तर: घ) hf = fLV²/(2gD)
Darcy–Weisbach gives hf = fLV²/(2gD), with f the Darcy friction factor.

A soil has field capacity 30%, permanent wilting point 12% (by dry weight) and dry unit weight 1.5 times that of water. The maximum depth of available water in a root zone of 0.8 m is:
सही उत्तर: घ) 216 mm
d = (γd/γw) × D × (FC − PWP) = 1.5 × 0.8 × 0.18 = 0.216 m = 216 mm.

-
A unit hydrograph is the direct runoff hydrograph resulting from:
सही उत्तर: ख) One unit depth (e.g. 1 cm) of effective rainfall of a specified duration spread uniformly over the catchment
A unit hydrograph corresponds to unit depth of excess rainfall of a given duration.

-
A canal has a CCA of 8000 ha and the intensity of irrigation for the Rabi season is 50%. The area to be irrigated in Rabi is:
सही उत्तर: क) 4000 ha
Area irrigated = CCA × intensity = 8000 × 0.5 = 4000 ha.

-
Water hammer in a pipeline is mainly caused by:
सही उत्तर: ख) Sudden closure of a valve
Sudden stopping of flow creates a pressure surge known as water hammer.
