Well=== pure water flows at 5.1 gpm thru 1/4 pipe , now valves have a slight orifice to slow the flow down some as a 1/4 valve most likely has a 1/16 orifice value , but that's just an educated guess as I don't know what valve u have , also im assuming your using pure water with a specific gravity of 1.0000 (yes it effects the rate) say hydraulic oil has a value of .0898 this will also slow the flow thru the valve

### Can you help me i need a pump that will produce 1 GPM thru 250' x 1/2" tubing @ 10psi

You can convert pipe size to gallons per minute of flow by calculating the cross-sectional area of the pipe and making some reasonable assumptions about pipe volume and the rate of flow. Pipe sizing is measured by the internal diameter of the pipe, not the overall outside diameter. Once determined, the overall volume can be calculated. Pipe flow is described in gallons per minute. Shorter lengths of pipe will have a greater flow than a longer length of the same diameter. This is caused by internal resistance of the pipe itself. By the same reasoning a larger diameter pipe will have a greater flow or GPM than a smaller pipe at the same pressure or flow rate. Pressure is described as pounds per square inch. The square-inch measurement is determined by the area of the pipe. The pounds are the amount of force that is placed on the liquid to push it through the enclosed space.With that background, you can estimate the flow based on the pipe size.
Find the cross-section area of the pipe. Area is equal to pi times the radius squared or a = 3.14 x r2. A two-inch diameter pipe would have a cross-section area of 3.14 x 12 or 3.14 square inches.
Understand that water has a certain pressure associated with the height of that water. One pound of water pressure, or 1 PSI, is equal to 2.31 feet of elevation in height. In other words, a 1-inch column or pipe of water that is 2.31 feet high will have a pressure of 1 PSI. The overall height -- not volume -- of the pipe corresponds to the pressure. A 6-inch diameter pipe that is 2.31 feet high will only have 1 PSI.
Find the volume of the 2-inch diameter pipe in Step 1 that has a length of 10 feet. Ten feet is equal to 120 inches. Multiply 3.14 square inches, the cross sectional area, times the length. The volume of the pipe is equal to 376.8 cubic inches of volume.
Convert cubic inches into cubic feet. One cubic foot equals 1,728 cubic inches. Divide 376.8 cubic inches by 1,728 cubic inches per cubic foot and the answer is .218 cubic feet. This means that the 2-inch diameter pipe that is 10 feet long has an internal volume of .218 cubic feet.
Calculate the amount of water that can be contained in the section of pipe at any given time. One cubic foot of water is equal to 7.48 gallons. Multiply 7.48 gallons by .218 cubic feet and the amount of water in the pipe is equal to 1.63 gallons.
Find the GPM if the flow of water is one foot per second. Multiply the one-foot per second flow by 60 seconds per minute and the flow is now 60 feet per minute. In other words the water will flow through the 10-foot pipe six full volumes for every minute. Since the piping contains 1.63 gallons per 10 feet of pipe, multiply 1.63 by six and the final GPM is equal to 9.78 GPM of water flow from the 2-inch diameter pipe.

### If a pump moves at 90 gallons per minute , what is the volumetric flow rate in units of cubic inches per second?

Assuming US gallons, 346.5 cubic inches per second.

The number will be slightly different for Canadian or Imperial gallons.

### High pressure due to back flow preventer

Add a variable regulator to the house side of the check valve. Also add a pressure tank between the regulator and the hot water heater.

### Can you use a draper submersible pump for a garden irrigation system to use with several sprinklers, does it provide enough water pressure on the outlet?

Here's how to tell.
Connect a tee to the outlet of the pump.
Install a pressure gauge in the tee.
Install a valve after the gauge.
Open the valve and start the pump.
Once water flows, close the valve slowly until you get 50 psi on the gauge.
Have a 5 gallon bucket nearby and measure how long it takes to fill the bucket at 50 psi.
If it fills the bucket in 30 seconds, you can attach heads to the pump that combined consume 10 gallons per minute.
Let me know how you do.

### 6.5hp 80gallon cfm psi?

MY DEAR FRIEND;
GALLON IS TO MEASURE THE VOLUME,BUT CFM(CUBIC FEET PER MINUTE) IS USED FOR FLOW.AND ALSO PSI IS FOR PRESSURE.THUS THEY ARE NOT ANY WAY RELATED.
IF IS IMPORTANT TO KNOW THOSE FACTORS, ESTIMATE THE TIME IT TAKES TO FILL THE TANK AND MEASURE THE FLOW AND READ THE MAXIMUM PRESSURE AND THOSE WILL APPLY

### No problem, just looking for gal. per minute flow rate

It uses 1.2 gallons for each wash or rinse action in a cycle.  The water only runs until the 1.2 gallons amount is reached and then that water recycles through the pump for the duration of the action.  Start the dishwasher and time how long it takes until the water stops filling (not the entire time of the action).  Divide 1.2 by the number of minutes including seconds as a decimal fraction (i.e. 1 minute and 30 seconds = 1.5 minutes) to get the flow rate in gallons per minute (GPM).
