While performing a fire hazard survey on a structure in a non-hydrant area you need to estimate the water supply capacity of a stream adjacent to the structure as a possible drafting site. The stream is 5' wide and the average depth is 12". You observe that a leaf floating on the surface travels 10 feet in 30 seconds from the current. What is the approximate flow rate in gallons per minute (GPM) of the stream?
