An operating log indicates that the average flow through a pump for ten hours is 285 gallons per minute. The following week, the same output is measured as 340 gallons per minute. What is the percent change?
Percent change is measured by the difference divided by the original capacity.
difference = new - old = 340-285=55 gpm
old capacity = 285 gpm
So
Percentage change = 55/285*100%
19
To find the percent change, you need to first calculate the difference between the two values and then express it as a percentage of the original value.
Let's calculate the difference:
Difference = New Value - Original Value
Original Value = 285 gallons per minute
New Value = 340 gallons per minute
Difference = 340 - 285 = 55
So, the difference is 55 gallons per minute.
Now, we can calculate the percent change:
Percent Change = (Difference / Original Value) * 100
Percent Change = (55 / 285) * 100 ≈ 19.3%
Therefore, the percent change is approximately 19.3%.
