Children are one of the major concerns of environmental exposure. Compare CDIs for a 10 month old child and an adult female drinking water contaminant with 10 mg/L of nitrate (as N). Assume a 1-year exposure time, a 1-year averaging time for both the child and adult, and the weight for the child is that of a 6 to 11 month old.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
