Correct Answer : 168 – (total Bharai – total Jharai) / Total area to be irrigated by the water-course
Explanation : The distribution is done on the basis of seven-day rotation i.e. 24 x 7 = 168 hours.
The bharai time is debited from the common pool time of 168 hours and that value of bharai which is not efficient for field applications, the tail end farmer is compensated and allowed a certain recovery of the bharai time is called jharai.
Hence, the formula for Flow Time for a unit area of a land holding is given as –
FT = 168 – (total Bharai – total Jharai) / Total area to be irrigated by the water-course.
