Can a square be a cross section of a square pyramid?
Can a square be a cross section of a square pyramid?
Let us look at a square pyramid (has a square base). Imagine a vertical plane cutting through the pyramid perpendicular to that base. If you sliced the pyramid parallel to the base, the cross-section would be shaped like a square (base). Now, cut the pyramid perpendicular to the base, but NOT at the vertex.
Can a shape have more than one cross section?
A single solid figure can be sliced to produce numerous cross sections of different forms. In the diagrams below, the sword represents the “slicing” plane. The solid object is a right rectangular prism. The maximum number of “sides” of a cross section equals the number of faces (surfaces) of the solid.
What is the cross section of a square prism?
The cross section is a rectangle. The cross section of any right prism parallel to its base is congruent to the base. Figure 2 shows the cross section of a right rectangular prism perpendicular to its base. The cross section is a rectangle….
| Common Core Standards Cross Sections | |

What is cross section of a pipe?
Pipe cross-sectional area is the area of a circle as seen when looking at the end of a pipe. The area varies directly with the square of the inside diameter. When one speaks of a one inch pipe, it is a nominal one inch; the true inside diameter usually is not 1 inch.
What is the difference between area and cross sectional area?
Area is somewhat that is occupied by an object when it is resting on a surface i.e area is the space which is used by the object. Whereas cross-sectional area is an area which we obtain when the same object is cut into two pieces.
What is cross section of a conductor?
A cross section is the two-dimensional area you would get by cutting through the a conductor with a plane. For eg., a cylindrical conductor, if cut the normal way, has a circular cross section.
What is the formula for area of a pipe?
Plug in L and D into the following equation to calculate the surface area of the pipe: 3.14 x L x D. For example, if you had a pipe with a length of 20 feet and a diameter of 2 feet, you would get 3.14 x 20 x 2 and find that the surface area of the pipe equals 125.6 square feet.
What is the unit of flow rate?
In S.I. units (International System of Units), volume flow rate has units of meters cubed per second, m 3 s \dfrac{\text m^3}{\text s} sm3start fraction, start text, m, end text, cubed, divided by, start text, s, end text, end fraction, since it tells you the number of cubic meters of fluid that flow per second.
What is a normal gpm for a house?
A toilet will normally use about 2-3 gallons per minute (gpm), a shower from 1.5 to 3.0 gpm, a bathroom or kitchen faucet from 2-3 gpm, a dishwasher from 2-4 gpm, and a washing machine from 3-5 gpm.
How many GPM will a 3/4 pipe flow?
| Assume Average Pressure. (20-100PSI) About 12f/s flow velocity | ||
|---|---|---|
| Sch 40 Pipe Size | ID (range) | GPM (with minimal pressure loss & noise) |
| 1/2″ | .50-.60″ | 14 gpm |
| 3/4″ | .75-.85″ | 23 gpm |
| 1″ | 1.00-1.03″ | 37 gpm |
How many GPM can a 4 Drain handle?
1106.2 Size of Storm Drain Piping
| PIPE SIZE (inches) | CAPACITY (gpm) | |
|---|---|---|
| 3 | 87 | 111 |
| 4 | 180 | 231 |
| 5 | 311 | 331 |
| 6 | 538 | 689 |
How many GPM can go through a 2 inch pipe?
850 gallons per minute
How do I calculate GPM?
The formula to find GPM is 60 divided by the seconds it takes to fill a one-gallon container (60 / seconds = GPM). Example: The one-gallon container fills in 5 seconds, breakdown: 60 divided by 5 equals 12 gallons per minute.
How many gpm do I need?
We suggest using 2.5 gpm for a shower and 1.0 gpm for a bathroom as a reference point in determining your total simultaneous water needs.
Is 10 gpm a good well?
10 GPM is probably a good nominal size for you, although 7 is good for many. A 1/2 HP 10 GPM may be best if your water level is 75 ft or closer.
Can you convert GPM to PSI?
PSI can’t be directly converted to GPM; these are two different units of measure. PSI measures pressure and GPM measures flow rate. But if other variables are known, the water’s flow rate in GPM can be calculated with the help of the Bernoulli equation for incompressible fluid and careful unit conversion.
What is more important PSI or GPM?
GPM is usually more important to contractors than PSI. Since most contractors use cleaning chemicals to do all of the cleaning, their job becomes one primarily of rinsing the dirt away.
What is the gpm flow rate?
GPM means Gallons Per Minute. Also known as “flow rate”, GPM is a measure of how many gallons of water flow out of your shower head each minute. This means no more than 2.5 gallons of water should flow out each minute.
How many GPM can a fire hydrant flow?
| CLASS | Hydrants that on individual test usually have a flow capacity of: |
|---|---|
| CLASS AA | 1,500 gpm or greater |
| CLASS A | 1,000 gpm or greater |
| CLASS B | 500 to 1,000 gpm |
| CLASS C | <500 gpm |
Is 2.5 gpm low flow?
Unfortunately, there is no firm definition of low-flow, but it’s generally accepted that anything using 1.5 gallons per minute (gpm) or less is considered “ultra low flow,” while anything using 2.5 gallons per minute to 1.5 gallons per minute is considered “low flow.” Nowadays, thanks to standards set by the government …
Is 2.5 gpm a good well?
5 gpm (two fixtures running simultaneously at 2.5 gpm) is a good estimate of peak demand, for the typical household. Water wells that reliably yield 5 gpm should be able to meet peak and daily needs for most residences. Wells yielding less than 5 gpm, however, are sometimes the only water source available.
