How many days will fish hatchery have to contain river water

Reference no: EM13305818

If the initial concentration of parathion in the runoff from the agricultural field is 3 ppb, the velocity of the river is 2.3 miles/day, how many days will the fish hatchery have to contain river water in holding tanks until the parathion concentration reaches 5 ppt? Assume that the fish hatchery removes the river 5 miles downstream from the agricultural fields. T = 25 oC.
