Gallons per minute to Cubic kilometers per second conversion

How to convert gallons per minute to cubic kilometers per second?

To convert 1 gallon per minute (GPM) to cubic kilometers per second (km³/s), you need to understand the relationships between the different units of measure:

1 Gallon = 3.78541 Liters 1 Liter = 0.001 Cubic Meters 1 Cubic Meter = 10⁻⁹ Cubic Kilometers

Now let's find the conversion factor:

1. Convert gallons to liters: $1 \, \text{gallon} = 3.78541 \, \text{liters}$

2. Convert liters to cubic meters: $3.78541 \, \text{liters} \times 0.001 = 0.00378541 \, \text{cubic meters}$

3. Since we want to get flow rate, first convert per minute to per second by dividing by 60: $\left(0.00378541 \, \text{cubic meters per minute}\right) / 60 = 6.30901667 \times 10^{-5} \, \text{cubic meters per second}$

4. Convert cubic meters to cubic kilometers: $6.30901667 \times 10^{-5} \, \text{cubic meters} \times 10^{-9} = 6.30901667 \times 10^{-14} \, \text{cubic kilometers}$

Therefore: $1 \, \text{GPM} = 6.30901667 \times 10^{-14} \, \text{km}³/\text{s}$

Real World Examples of Gallons per Minute (GPM)

1. Residential Water Flow: A typical household faucet has a flow rate of about 2.2 GPM.
2. Firefighting: Fire hydrants can deliver between 500 to 1500 GPM depending on the system and location.
3. Garden Hose: A typical garden hose flow rate can range from 9 to 17 GPM depending on the hose diameter and water pressure.
4. Pumping Systems: Industrial water pumps can have flow rates that vary widely, from several hundred to several thousand GPM.
5. Swimming Pools: Pool pumps for residential swimming pools can vary, often around 20 to 100 GPM to circulate and filter the pool water effectively.

These examples highlight the variety of applications and scales at which flow rate measurements in GPM are commonly used.
