If a pipe carries 180 gallons per minute, what is the flow per hour?

Explanation:
Converting flow rate from per minute to per hour uses the fact that there are 60 minutes in an hour. Multiply the per-minute rate by 60: 180 gallons per minute × 60 minutes = 10,800 gallons per hour. The other numbers would come from different per-minute rates (for example, 140 gpm would give 8,400 gph; 30 gpm would give 1,800 gph; 200 gpm would give 12,000 gph). Since the rate is 180 gallons per minute, the hourly flow is 10,800 gallons per hour.
