To calculate the percent error for the increase in flow rate, you first determine the change in flow rate and then compare it to the original flow rate.

The initial flow rate is 2.0 LPM, and it increases to 2.25 LPM. The change in flow rate can be calculated as follows:

Change in flow rate = New flow rate - Original flow rate

Change in flow rate = 2.25 LPM - 2.0 LPM = 0.25 LPM.

Next, you compute the percent change relative to the original flow rate. The formula for percent change is given by:

Percent Change = (Change in flow rate / Original flow rate) × 100.

Now, substituting the values:

Percent Change = (0.25 LPM / 2.0 LPM) × 100

Percent Change = 0.125 × 100

Percent Change = 12.5%.

Thus, the percent error for the flow rate increase from 2.0 LPM to 2.25 LPM is 12.5%. This calculation illustrates the significance of comparing the change to the initial value, providing insight into how substantial that change is in relation to where it started.
