The 'Kor watering' in irrigation is:
सही उत्तर: क) The first watering after the plants have grown a few centimetres
Kor watering is the first watering given after the crop has grown a few centimetres, and is usually the heaviest.

Cavitation in hydraulic machines occurs when the local pressure falls below the:
सही उत्तर: ख) Vapour pressure of the liquid
When pressure drops below vapour pressure, vapour bubbles form and collapse, causing cavitation damage.

In irrigation engineering, 'delta' of a crop refers to:
सही उत्तर: घ) Total depth of water required by the crop during its base period
Delta is the total depth of water needed by a crop over its base period.

The theoretical velocity of a jet from an orifice under a constant head of 5 m (g = 9.81 m/s²) is about:
सही उत्तर: घ) 9.90 m/s
By Torricelli's theorem V = √(2gH) = √(2 × 9.81 × 5) ≈ 9.90 m/s.

A cross-drainage work in which the natural drain passes over the irrigation canal is called a:
सही उत्तर: ख) Super passage

Which of the following is a Rabi crop?
सही उत्तर: क) Wheat
Wheat is sown in winter (October–November) and harvested in spring, so it is a Rabi crop.

-
The coefficient of discharge (Cd) of an orifice is related to the coefficient of contraction (Cc) and coefficient of velocity (Cv) as:
सही उत्तर: ग) Cd = Cc × Cv
Actual discharge = Cc × area × Cv × theoretical velocity, so Cd = Cc × Cv.

-
A floating body is in stable equilibrium when:
सही उत्तर: क) Its metacentre lies above its centre of gravity
Positive metacentric height (M above G) gives a restoring couple, so the body is stable.

-
Which method of irrigation generally gives the highest water application efficiency?
सही उत्तर: ग) Drip (trickle) irrigation
Drip irrigation delivers water directly to the root zone with very little runoff or deep percolation loss.
