What was the average gpm flow for that day? The average flow per minute is desired. Therefore, the denominator must reflect the number of minutes represented by the totalizer flow: Average low, -- Tot. 000gallons 1440 minutes 31 CALCULATING AVERAGE FLOWS USING TOTALIZER INFORMATION When totalizer data is used to calculate average flows, the number in the denominator depends on the time W e desired. If you desire to know the average flow per minute, divide by the number of minutes represented by the totalizer flow.

Examples 2 and 3 illustrate how to use dimensional analysis in checking the problem set up. Refer to Chapter 15 in Basic Math ~once$s for a fimher discussion of dimensional analysis.
