Water Flow and Volume Calculations

Garden Hose and Pond Volume

• A garden hose has a flow rate of 1 gallon per minute.
• It takes 3 hours to fill a pond.
• To calculate the pond's volume, first, convert hours to minutes: 3 hours * 60 minutes/hour = 180 minutes.
• The pond's volume is the flow rate multiplied by the time: 1 gallon/minute * 180 minutes = 180 gallons.

Concrete Truck Discharge Time

• A concrete truck has a volume of 10 cubic yards.
• The truck discharges concrete at 100 cubic feet per minute.
• Convert cubic yards to cubic feet: 10 cubic yards * 27 cubic feet/cubic yard = 270 cubic feet.
• The time to empty the truck is the total volume divided by the discharge rate: 270 cubic feet / 100 cubic feet/minute = 2.7 minutes.

Water Fountain Flow Rate

• A water fountain fills a 5-gallon tank in 10 minutes.
• The flow rate is the tank volume divided by the filling time: 5 gallons / 10 minutes = 0.5 gallons per minute.

Faucet Water Collection

• A faucet has a flow rate of 1.5 gallons per minute.
• The total volume collected after 20 minutes is the flow rate multiplied by time: 1.5 gallons/minute * 20 minutes = 30 gallons.

Fire Hydrant Water Release

• A fire hydrant releases water at 120 gallons per minute.
• The total water released in 15 minutes is the flow rate multiplied by time: 120 gallons/minute * 15 minutes = 1800 gallons.

Pump Draining a Tank

• A pump drains a tank at 50 cubic feet per minute.
• The tank has a volume of 2,000 cubic feet.
• The time to drain the tank is the total volume divided by the drainage rate: 2,000 cubic feet / 50 cubic feet/minute = 40 minutes.

Swimming Pool Filling Time

• A swimming pool is filled at a rate of 0.6 gallons per second.
• It takes 4 hours to fill the pool.
• Convert hours to seconds: 4 hours * 60 minutes/hour * 60 seconds/minute = 14,400 seconds.
• The pool's total volume is the flow rate multiplied by the filling time: 0.6 gallons/second * 14,400 seconds = 8,640 gallons.

Water Tank Filling Rate

• A water tank has a capacity of 500 gallons.
• It takes 40 minutes to fill the tank using a pump.
• The pump's flow rate is the tank volume divided by the filling time: 500 gallons / 40 minutes = 12.5 gallons per minute.

Hose Flow Rate

• A hose fills a 55-gallon drum in 22 minutes.
• The hose's flow rate is the drum volume divided by the filling time: 55 gallons / 22 minutes = 2.5 gallons per minute.

River Water Flow

• A river flows at 300 cubic feet per second.
• To calculate the water flow in 1 hour, convert hours to seconds: 1 hour * 60 minutes/hour * 60 seconds/minute = 3,600 seconds.
• The total water flow in 1 hour is the flow rate multiplied by time: 300 cubic feet/second * 3,600 seconds = 1,080,000 cubic feet.
