The water in a garden hose flows at a rate of 10.0 liters per minute. What is the flow rate in gallons per hour? (1gal=3.79L)

Answer 1

This is a problem where you want to use dimensional analysis (unit factor method). To do this, we to first know some conversion factors. The ones we need are:

1 gal = 3.79 L

60 min = 1 hr

10.0 L/min x 60 min/hr x 1 gal/3.79 L = 158 gal/hr

Looking at this step by step:

10.0 L/min x 60 min/hr = 600 L/hr (minutes cancel)

600 L/hr x 1 gal/3.79 L = 158 gal/hr (liters cancel)
