How many gallons come out of a hose per hour? The standard 5/8-inch garden hose delivers 17 gallons per minute. Larger hoses, such as a 3/4-inch hose, use up to 23 gallons per minute. A 1/2-inch garden hose delivers about 9 gallons of water per minute.
How many gallons per second does a fire hose pump?
The 1 1/2-inch double jacket fire hose provides 5.06 gallons per minute per dry pound of hose (150 GPM / 29.6 lbs dry = 5.06 GPM/pound). While 150 GPM may be plenty in many situations, this hose trades ease of use for lower flow rates. Moreover, how much water pressure comes out of a fire hydrant?

How many gallons of water does a fire hose put out?
Generally 1500 - 3000 gallons is fairly normal. Fire apparatus also have the ability to draft water from nearby external water sources such as pools and ponds. The apparatus will literally suck water from those sources that may be used for extinguishment. The hoses used to do this are called hard suctions.
What is the average flow rate of a fire hose?
Australian Standards Ensure Reliability from Fire Hose Reels Most hose reels are designed to deliver 30 litres of water a minute or 0.33 litres every second, but Australian Standards specify that the 19mm fire hoses have to be able to deliver at least 0.45 litres of water per second, at 220kPa.
How many gallons a minute does a hose use?
A typical garden hose flow rate is usually between 6 and 12 gallons per minute. The average garden hose GPM would be around 9, but this can vary depending on the type of hose.
How many gallons of water does the hose supply in 10 minutes?
There are several factors that affect garden hose flow rate. These include the diameter of the hose, the level of water pressure, and the length of the hose. A typical garden hose flow rate is usually between 9 and 17 gallons per minute.
How much water does a 1 3 4 fire hose flow?
In real life, an 1-3/4” handline can comfortably and safely flow from 100 to 180-GPM on the fireground, and any flows over 150-GPM are best run through low pressure combination or smooth bore nozzles to reduce nozzle reaction forces.
How many GPM can a 1/2 hose flow?
A 25-foot, 1/2-inch diameter hose attached to a faucet that supplies water at 40 psi has a flow rate of 24 gallons per minute, while a 100-foot hose only has a flow rate of 6 gallons per minute.

How many gallons per minute does a sprinkler head use?
What is the average flow rate? The standard sprinkler flow rates, in general, are from 4 gallons per minute (gpm) from a 5/32-inch nozzle at 30 pounds pressures to over 11 gpm from a 7/32-inch nozzle at 70 pounds pressures.
How many gallons per minute does a fire hose pump?
depends on size of hose and pump pressure. Typical Flows for hand lines – 1 inch hose 30–60 gpm; 1.5 inch hose 125 gpm; 1.75 inch hose 200 gpm; 2.5 inch hose 250–300 gpm. For supply lines depends on the water system, but a 4 inch supply line could be 1000–1500 gpm. Howdy, Red Line hose is rated at 150 gallons a minute.
How high can a fire truck pump water?
How high can a fire hose shoot vertically? Between 75 feet and 100 feet straight up, depending on water pressure. In practice, though, firefighters on the ground rarely attempt to reach higher than 40 feet with hoses.
How many PSI does a fire truck pump?
Most fire pump discharges require 120-200 psi of pump discharge pressure for hose lines, nozzles and appliances. Low pressure nozzles allow for lower pump pressures to deliver the same flow rates. Water supply lines may require as little as 40-50 psi of engine pressure, up to 185 psi for large diameter supply hose.
How much does 1.75 Fire Hose weigh?
While it depends on the materials used to make the hose, the average weight of a hose of this diameter is 0.34 pounds per foot (or about 20 pounds per 50 feet of length ).

What is LDH hose?
LDH can be used for either supply lines or discharge lines. Five-inch hose flows twice as much as four-inch hose.
What is static pressure?
Many people think the static pressure is the number to look at when determining how good a fire hydrant is. This is misleading because it is measuring the water at rest.
Does the cost of a 5 inch hose go up?
One thing to consider if the choice is five-inch hose is to purchase it in 50-foot sections. Yes, the cost will go up somewhat because of the increased number of couplings, but the weight will go down by half.
Is LDH good for firefighters?
It’s no wonder firefighters in those days thought LDH was the best thing to happen to them since motorized apparatus. The fact is that LDH, as good as it is, will probably not max out the water supply from a decent hydrant by using just hydrant pressure. This especially holds true for four-inch hose.
