The correct answer is A. 637 hectares/m3/sec.
The outlet factor is the amount of water that needs to be discharged from a field per unit area per unit time to maintain the desired water depth. It is calculated as follows:
Outlet factor = kor depth / kor period
In this case, the kor depth is 190 mm and the kor period is 14 days. Therefore, the outlet factor is 190 mm / 14 days = 13.57 mm/day.
To convert this to hectares/m3/sec, we need to multiply by the conversion factor 1 hectare = 10,000 m2 and the conversion factor 1 day = 86,400 seconds. This gives us the outlet factor of 13.57 mm/day * 1 hectare/10,000 m2 * 86,400 seconds/day = 637 hectares/m3/sec.
The other options are incorrect because they do not take into account the kor depth or the kor period.
