I need to determine the cubic feet in a cylinder that has a circumference of 34'8" and a height of 16'2.5"

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.

cubic capacity is pye X radius squared X depth
that is 3.1416 X 5.33 squared by 1 .3 ft
that is 3.1416 X 28.408 X 1.3
that is 118.69 cubic ft
1 cubic ft = .0370 cubic yards
multiply 118.69 cubic ft =4.39c yards or you can convert the feet to yards first and then apply the formula
so that is 3.1416 X 1.77 squared =
3.1416 X 3.13= 9.83 sq yards X .43 yards =4.22 cubic yards
the difference is from how many decimal points you go to
for each number

Volumes are any three dimensional measurement...

I Seriously doubt that I could get Pi ("pie") to print...
But I'll just GIVE YOU the number (much simpler)
Pi = 3.14159

Inches, feet, yards or meters.. all the dimensions need to be in the same values... So if you have an inch "ruler"...
That is just fine...!!

Your first step would be to determine the diameter of the inside of your cylinder in inches...
CONVERT that to the RADIUS by DIVIDING by 2...
Multiply that RADIUS by itself and then by 3.1416 = area of circle in INCHES... (radius "squared" x Pi = (square inched)

Then MULTIPLY the height (in inched) by the AREA...
EQUALS THE VOLUME in CUBIC INCHES...!!



But I'll just GIVE YOU a REFERENCE (much simpler)
mathematical constant ?
Area of circle

7 cubic ft. capacity.
Measure the diameter of the tub using a measuring tape

1. Divide the diameter by two to get the radius
2. Measure the height of the tub in feet
3. Multiply the square of the radius with the height of tub and pi (3.14). (square of radius x height x pi)

The result would be the capacity of dryer in cubic feet.

The formula is V = Pi * R^2 * H where

R: radius
H: height
V: volume

So you need the radius and height in feet, and plug them into this formula. Or you can enter what you know, in feet, to this calculator, and it will give the unknown

Hi Paula:
A mathematical logic question.
You need to get all of the measurements in the same units.
- A cubic yard is 1 yard x 1 yard x 1 yard
- equals 3 ft x 3 ft x 3 ft
- equals 27 cubic feet,
so once you have the volume of the pipe in cubic feet, you divide by 27 to get the volume in cubic yards.
- Volume of a cylinder (the pipe) is the cross sectional area X length.
- Area equals Pi x r squared.
- equals 22/7 x 1 x 1
equals 3.14#####
times length (20)
equals 62.857### cubic feet volume
divide by 27 cubic feet
equals 2.328### cubic yards.

- The answer is always the easy part.
- what is important is knowing exactly what the question is, and
- determing what calculations are needed to get the answer.

Wasn't that better than if I'd just said 2 1/3 cubic yards?
Cheers

Just a little over 53.3 gallons

good question easily answered

18165.71428571427 calclation output as radius 17 inch
and 20 height

21371.42857142855 calclation output as radius 20 inch
and 17 height

output is cubic inches
here it the calculation page i used

A pipe can be seen as two cylinders, one of "air" sitting inside the other, in this case lead.
To get the volume of a pipe you thus subtract the volume of the "air" cylinder from that of the lead cylinder.
Volume of a cylinder = area of circular cross section (or pi times square of the radius) times the height (or length) => ? * r2 * h
Volume of a pipe = Volume of cylinder 1 (outer diameter) - volume of cylinder 2 (inner diameter).

In this case; Volume of outer cylinder => inner diameter 1/2" (0.5") + pipe thickness 1/4" (0.25") = 3/4" (0.75") divided by 2 to get radius = 0.375".
3.14 (?) * 0.375 * 0.375 * 120(10 feet) = 53.01438 in3

Volume of inner cylinder => inner diameter 1/2" (0.5") divided by 2 to get radius = 0.25".
3.14 (?) * 0.25 * 0.25 * 120(10 feet) = 23.56194 in3

Volume of lead in this pipe = 53.01438 - 23.56194 = 29.45244 in3

Hope this helps ;)

Yes, you'll be o.k. They don't recommend anything over 3% difference, and your at about 1.8%. Speedo will read 61 mph when actually doing 60 mph. Have a look.
