1.Without taking any measurements, estimate how many gallons of water you use per day.
2.Calculate you Water Flow Rate flow in gallons per minute (GPM) as follows:
a.Take an empty gallon container (i.e. a milk container) and time how many seconds it takes fill the container at full faucet force under the bath tub faucet or the kitchen sink faucet which ever is easier.
b.Divide 60 seconds by the time it took to fill you gallon container ( round off to the nearest tenth) This is your Water Flow Rate in GPM.
Example 1: 35 seconds to fill a gallon container gives a Water Flow Rate of 1.7 GPM (60/35)
Example 2: 90 seconds to fill a gallon container gives Water Flow Rate of 0.7
3.Record for a 5 day consecutive period the amount of water you use (shower, bath, washing dishes by hand, brushing teeth, and washing face/hands) by multiplying the time you let the water run by your Water Flow Rate (GPM) from 2b. above. Assume two (2) gallons of water per toilet flush and 20 gallons of water per cloth washing load or automatic dish washing load. In addition, estimate the amount of water for use for cooking, watering plants and/or drinking (Miscellaneous).
4.Prepare a Data Sheet with your results using a computer spreadsheet, see attachment 1.
5.Calculate your Daily Water Usage ( DWU) by dividing the Total ( look at data sheet) by 5.
6.Based on your Daily Water Usage ( DWU) and your estimated water use per day, prepare a short but concise conclusion on your water usage habit ( be honest).
7.Your report should include the following:
a.your data sheet
b.a one page written explanation of your results and conclusions doubled spaced and in proper grammar, i.e. spelling. Punctuation. No abbreviations in the following format:
i.Hypothesis (educated guess) (JUST MAKE A GUESS)
ii.Procedures and Materials used experiment (i.e. the items discussed on this page)
iii.Results: Provide your results in table form like data sheet (an Excel, MSWorks, or Lotus spread sheet should be used).
iv.Discussion: your results as part of an analysis.
v.Sources of Error: Discuss at least 3 source of error.
