Consider the stock-flow example of a bathtub with the faucet open and running at a rate of 2.5 gallon/min. The outflow rate depends on the water depth as shown in the graph.
Determine the net flow (in gallons per minute) when the water depth is 5.5 inches.
Round your answer to the nearest 0.1 gallon per minute. Note that when the outflow exceeds the inflow, then the net flow is negative.
Net flow: gallons per minute
