As the summer intern for a company that manufactures nozzles for garden hoses, you are working on an adjustable hose nozzle project. Your design calls for a rotating head that has a number of cylindrical plugs that can be inserted into the hose opening. On a particular setting, the speed of the water passing around the plug is 5 times as large as the speed of the water in the hose. Determine the ratio of the plug radius (rplug) to the inside hose radius (r hose)
