What is the inflow rate in gallons per minute if water is being piped into a tank at 2 gallons per second?

To find the inflow rate in gallons per minute when water is being piped into a tank at 2 gallons per second, it is necessary to convert the rate from seconds to minutes. Since there are 60 seconds in a minute, you can multiply the flow rate by the number of seconds in a minute to obtain the inflow rate in gallons per minute.

Starting with the flow rate of 2 gallons per second, you would calculate as follows:

2 gallons/second × 60 seconds/minute = 120 gallons/minute.

Thus, the inflow rate is 120 gallons per minute, which makes that the correct answer. This calculation is key in interpreting flow rates, as it provides a consistent measure over a longer time frame (minutes) rather than a shorter one (seconds), aligning with common units used for flow rates.
