Perform the following conversions: (e) 22.50 gal/min to L/s

검증된 단계별 안내
1
Identify the conversion factors needed: 1 gallon = 3.78541 liters and 1 minute = 60 seconds.
Convert gallons to liters using the conversion factor: multiply 22.50 gal/min by 3.78541 L/gal.
Convert minutes to seconds by dividing the result from the previous step by 60 seconds/min.
Combine the conversions to express the flow rate in liters per second (L/s).
Ensure the units cancel appropriately, leaving you with the desired unit of L/s.

Conversion Factors

Flow Rate

Flow rate is a measure of the volume of fluid that passes through a given surface per unit of time. It is commonly expressed in units such as gallons per minute (gal/min) or liters per second (L/s). Understanding flow rate is essential in various applications, including engineering and environmental science, as it helps in assessing the efficiency of fluid systems.

Metric and Imperial Units

Metric and imperial units are two different systems of measurement. The metric system, used widely in science, is based on units like liters and meters, while the imperial system includes units like gallons and feet. Familiarity with both systems is crucial for performing conversions accurately, especially in scientific contexts where precise measurements are necessary.
