Here are some tips on how to save by calculating your gallons per minute consumption of water and gasoline.

For calculating gallons per minute of water. Most of the faucets and showerheads now have a prefixed flow rate. As of 1992, the required flow rate is not more than 2.2 GPM at 60 PSI. To manually compute the flow rates of shower heads and faucets, you can take a container and fill it with water from a running faucet of shower head  for 10 seconds. Make sure that the water is in full blast. Close the faucet or shower head and measure the amount of water in the container. Convert your measured water in gallons. Lastly, multiply the derived amount in gallons by 6. The product is the amount of consumed water in gallons per minute.

For measuring gallons per minute of gasoline. For this, you will need a notebook, a pen and a calculator.

  • Keep track of the time you drive within a week. Keep a constant log of your commuting time from day to day. Note the time of your departure to the time you were able to park. Compute for your travel time. Keep the record intact, and place the notebook in your glove compartment for an easy access.
  • Take note of how much you gas up. Know how much gas you spend in a week. To make it easier, go on a full tank of gasoline on your first day. If the gas runs out and you need to fill up again, take note of how much gas you had to refill. During your seventh day, add your accumulated gas consumption. Write it down together with the driving time.
  • Convert the driving time into minutes. Take note of the total driving time within the week. Convert the number of hours into minutes; multiply the number of hours by 60. Add the values to give you the figures reflecting the length of time you drove in minutes.
  • Compute the amount of the gasoline you consumed. Add all the gasoline you used starting from the first full tank up to the succeeding refills. Make sure that you convert them in gallons.
  • Calculate your gasoline gallons per minute. Divide the number of gallons you have consumed with the number of hours you drove on the road. This will reflect your gas gallons per minute.

Do this test for a number of times all year round to see your water and gas accumulation patterns. Make the necessary changes in your consumption to help maintain the consumption and expenditures for water and gas to the minimum.
