Water Calculations

WATER CALCULATIONS FOR LESSON 8 OF OPERATION WATER POLLUTION

1 tonne = 1000 kg

2.7 million tonnes x 1000 kg/1 tonne = 2 700 000 000 kg plastic for water bottles and, therefore, 2 700 000 000 kg PETs

2 700 000 000 kg PET x 17.5 kg water/1 kg PET = 47 250 000 000 kg water

47 250 000 000 kg water x 1 tonne/1000 kg = 47 250 000 tonnes water

5 511 556 lbs water in Olympic sized pool

5 511 556 lbs ÷ 1 kg/2.2 lbs = 2 505 252 kg water

2 505 252 kg water x 1 tonne/1000 kg = 2 505 tonnes water in Olympic sized pool

47 250 000 tonnes water ÷ 2 505 tonnes = 18 862 Olympic sized pools

1 year = 365 days 18 862 pools ÷ 365 days = 51.6 years
