If your lawn is 21.0 ft wide and 20.0 ft long, and each square foot of lawn accumulates 1350 new snow flakes every minute. How m
klemol [59]
Let us start with the total area of the lawn. Area= width x length, ie, 21 x 20 = 420 sq. ft.   Snow flakes per square foot per minute = 1350  So Snow flakes for 420 sq.feet per minute = 420 x 1350 = 567000.   Snow flakes for 1 hour = 567000 x 60 = 34020000 (60 minutes)  Weight of 34020000 snow flakes = 34020000 x 1.60 = 54432000mg.  To convert it into kilograms, divide this number by 1000000 (1 kilogram = 1000000 milligrams)  Thus 54432000/1000000 = 54.432 kilograms or 54 kilograms and 432 grams.

Chlorine is the most widely used disinfectant for killing pathogens during water treatment. Determine the kilograms of chlorine
makkiz [27]

Explanation:

The given data is as follows.

    Flow of chlorine (Q) = 10,000 m^{3}/day

Amount of liter present per day is as follows.

                  10,000 \times 10^{3} l/day

It is given that dosage of chlorine will be as follows.

                   10 mg/l = 10 \times 10^{-6} kg/l

Therefore, total chlorine requirement is as follows.

          Total chlorine requirement = (10,000 \times 10^{3}) \times (10 \times 10^{-6}) kg/day

                                        = 100 kg/day

Thus, we can conclude that the kilograms of chlorine used daily at the given water treatment plant is 100 kg/day.
