Question

In this experiment you will measure how much water you can save in a shower. First, measure the rate of water use as follows: Fill a gallon jug with water and pour it into a bucket. Mark the 1-gallon level with a tape or crayon and empty the bucket. Now run the shower water at the rate you normally use and, with a stopwatch, measure the time in seconds required to deliver 1 gallon of water into the bucket. (have someone outside the shower run the stopwatch so it does not get wet.) Rate of Flow = _______ sec/gal In the morning, measure the time required to take your ordinary shower: __________ sec. Calculate Water Used in Time in Shower (Sec) = ______ gal Ordinary Shower Rate of Flow (Sec/gal) The next day, take a shower in the following manner. Turn the water on and wet yourself completely. Then turn the water off while you soap yourself. Turn the water back on to yourself rinse. Measure the time the water was running: __________ sec. The difference between the two times is the time saved in the conserving shower: ___________ sec. Calculate the savings: Water saved (gallons) = Time saved in the Conserving shower (sec)/Rate of flow of Shower water (sec/gal) = __________ gal

Explanation / Answer

This is a type of problems in which it can be having the varied answer according to different person but i am taking here a general case. for the case first we have to calculate the rate of flow so

If the taking the general case then the flow rate per minute is 15 litres or 3.9 gallon.

now if take the case of sec then 15/60= .25 litres/ sec or 17.38 sec/gallon

now rate of flow is 17.38 sec/ gallon

and then water used in ordinary shower is 300/17.38= 2.64 gallon or 10 litres.

----------------------------------------------------------------------------------------------------------

For the case of conservation of water then we are estimating the following values as-

time of running the water=300 sec or 5 minutes

time for saved the water= 2 minutes or 120 sec

then water saved= 120/2.1=1.84 gallon OR 7 litres

The answer may be different because the standard of observation may be different because the dimension of apparatus like mug or bucket will be different for different experiment performed by individual.
