Hi,
Do you mean circumference or diameter??
The diameter of a 5 foot circle is 5 feet...

otherwise the circumference is 5 X 3.142

### 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.

### What is the volume in liters of a water tank with ....... radius 2 feet 6 inches height 5 feet 2 inches

Assuming you are correct that the radius is 2' 6" and not the diameter.
Convert the inches to centimetres
1" = 2.54 Cms
Radius = 2' 6" = 30" X 2.54 = 76.2 Cms
Height = 5' 2" = 62" X 2.54 = 157.48 Cms
Volume of cylinder = Pi x radius squared x height
3.142 x 76.2 x 76.2 x 157.48 = 2,873,038.9 cc
Divide by 1000 to find how many litres (interest note 1000cc car engine is 1 litre)
2,873,039 cc / 1000 = 2,873 litres

### All these answers are for square objects. How do I find the measurements of a round object, i.e. a cement mixer?

Hi Debbie:
You still get to use your calculator, but you need to use the mathematical formulae dealing with circles.
Area = pi times r squared
Volume of a cylinder = Area (of one end) times length.

For your cement mixer, (Average the diameter for simplicity)
All of the measurements need to be in the same units, lets use inches, then convert it to cubic feet.....
the volume would be:
pi (22 divided by 7)
times
1/2 diameter
times
1/2 diameter
times
depth

For my ancient mixer that would be:
22 / 7 x 10" x 10" x 22" = 6,914 cubic inches
1 cubic foot equals 12" x 12" x 12" equals 1728 cubic inches.
6,914 divided by 1728 equals 4 cubic feet.

Now we don't fill it right up, but that is its capacity.

Hope that helps.
By the way, my mixer likes 10 shovel fulls of navvy, 2 shovels of type 10 cement, and about 2 quarts of water to get a nice mix.
I do the water first,
then 5 navvy
then 2 cement
then another 5 navvy,
then just enough water to get the right consistency.
Cheerfuls!

### What are the maximum number of joints a recommended in the dryer vent pipe for these electric Ge profile dryers.

Codes typically require that the dryer duct be no more than 25 feet long. It should be 2.5 feet shorter than 25 feet for every 45-degree bend and 5 feet shorter for every 90-degree bend. If the duct is more than 25 feet in length, the system requires a booster fan or a high-output dryer. Ducts should be smooth metal with a minimum diameter of 4". Flexible ducts shouldn't be used, since they collect more lint and can easily be crushed, impeding airflow and potentially starting lint fires. The ducts shouldn't have screws or connectors, which could collect lint, blocking the flow of combustion gases. Backdrafting can occur if the ducts are blocked, sending harmful carbon monoxide back into the home.

### How mush cu. is it

cubic feet is the volume of the drum. Volume of a cylinder is diameter squared/2 x depth EG: 2' diameter x2' diameter =4 4/2=2... 2x2(depth)=4cubic feet
