To determine the gallons per minute (GPM) in a 6-hole system at 80 psi, you would need to know the specific flow rate for each hole based on the orifice size and design. Generally, flow rates can vary, but a common estimate might be around 5-10 GPM per hole at that pressure. Therefore, for a 6-hole system, the total GPM could range from approximately 30 to 60 GPM, depending on the specific conditions and equipment used. For precise calculations, consult manufacturer specifications or flow rate charts for the specific system.
"Normal Pressure" varies depending on where you live. Most municipalities try to provide water between 40 and 80 psi. That's a pretty big range. How much water comes out of your garden hose varies depending on your service pressure, the length of hose, how much water your using in your house at that moment, and where the hose is located in relation to your water service. The most accurate way for you to figure it out is to take a 5 gallon bucket (the orange Home Depot buckets are about 5 gals) and time how long it takes you to fill it. If it takes 1 minute to fill 5 gallons then you're only getting a flow rate of 5 gallons per minute (this would be uncommonly slow). If it takes 30 seconds, then you're at 10 gpm. 20 seconds -> 15 gpm, etc. If you don't need to be terribly accurate, it's pretty safe to assume somewhere between 15 to 30 gpm for normal residential service. 15 gpm is on the lame end and 30 gpm would be pretty impressive for a garden hose.

The operation to get from 80 to 8 is division. Divide 80 by ten, and the answer is 8.
First, calculate the volume of the hole in cubic inches: (18 \times 48 \times 12 = 10,368) cubic inches. Since there are 1,728 cubic inches in a cubic foot, convert the volume to cubic feet: (10,368 \div 1,728 \approx 6) cubic feet. An 80-pound bag of material typically covers about 0.6 cubic feet, so you would need approximately (6 \div 0.6 = 10) bags to fill the hole.

To find the maximum flow you would need to know the maximum pressure. A typical fire nozzle pressure would be up to 100 psi with a diameter of 1 to 1.25 inches. The GPM would be between 300 GPM and 460 GPM through the nozzle. If it were simply a 3-inch pipe with an oversized pump, running at 100 psi with no nozzle, you could (in theory) move over 3,000 GPM through the pipe (ignoring friction loss). Even at 80 psi, a master stream through a 2-inch nozzle moves over 1,000 GPM.
To calculate the static pressure at a depth of 25 feet with a psi of 80, we need to consider that 1 psi corresponds to approximately 2.31 feet of water. Therefore, the pressure in feet of water at 80 psi is 80 psi × 2.31 feet/psi = 184.8 feet. At a depth of 25 feet, the static pressure would be the sum of the atmospheric pressure (typically 14.7 psi at sea level) and the pressure from the water column. In this case, the static pressure at 25 feet is approximately 80 psi, assuming the measurement is taken at that depth.

That will depend on the application and weight rating of the tire. A passenger car tire would be about 35 psi. A truck tire would be 80 psi.

The recommended psi for a bike tire is typically between 80-100 psi.
To determine the gallons per minute (gpm) at 80 psi, you need to consider the flow characteristics of the specific system or device in question, as flow rates can vary widely based on factors like pipe size, fittings, and fluid type. For example, a standard garden hose might deliver anywhere from 5 to 10 gpm at that pressure, while a larger diameter pipe could deliver significantly more. For an accurate measurement, it's best to refer to manufacturer specifications or conduct a flow test.
The average psi recommended for bike tires is typically between 80 and 100 psi.
