Question

What is the correct formula for Flow Time in an hour for an individual farmer?

(a) (FT for the unit area) x (area of farmer’s fields) + (his bharai – his jharai)

(b) (FT for the unit area) x (area of farmer’s fields) – (his bharai – his jharai)

(c) FT for the unit area + (his bharai – his jharai)

(d) FT for the unit area – (his bharai – his jharai)

The question was posed to me in unit test.

The origin of the question is Canal Regulation in division Canal Irrigation System of Irrigation Engineering

Answer 1

The correct option is (a) (FT for the unit area) x (area of farmer’s fields) + (his bharai – his jharai)

Best explanation: The formula for the flow time an hour for an individual farmer after the allowance of Bharai and Jharai timings is –

(FT for the unit area) x (area of farmer’s fields) + (his bharai – his jharai)

Bharai is generally zero in case of the tail (i.e. the last farmer) and Jharai is usually zero for all except for the tail.
