## How do you convert diameter to length?

Calculating Diameter From the Radius The radius is the length from the center of a circle to the edge.

Therefore, if you know the radius, multiply it by two to determine the diameter (diameter = 2 x radius)..

## How do you know how much wire is in a spool?

Add the diameter of the wire to the diameter of the drum. Multiply this figure by the diameter of the wire. Multiply this figure by the width of the drum. Multiply the current figure by the diameter of the wire; for example, if the diameter of the wire is 1.5 inches, this figure would be multiplied by 1.5.

## How many meters are in a roll?

100 metresA full roll of lining fabric is about 100 metres but still only weighs 25kgs as the fabric is thinner and lighter in weight. Common fabric widths are: 150cm (60″)

## Which wire has more resistance thick or thin?

The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of the cross section of a wire is inversely proportional .

## How is roll diameter calculated?

Can you help me? I want to be able to plug the formula in a spread sheet and to be able to input a core diameter, a film thickness and a total length and get a roll diameter. R = √(36000 × 0.005/π + 32) = √(57.30 + 9) = 8.14 inches. Thus the diameter of the roll is 2 × 6.95 = 16.28 inches.

## How much fabric is on a roll?

I see that your minimum order size is 1 roll, but how many yards are on each roll? Rolls typically start at 50 yards; however, it depends on the product. Please see the individual product pages for roll sizes or contact us.

## How much wire do I need for a 2000 square foot house?

Costs also vary by area, as some electricians will charge per hour while others charge by the job. On average, the cost to wire a home is around $4 per square foot. Therefore, to rewire a 2,000 square foot home, the total cost would be about $8,000.

## How many feet does it take to fence 10 acres?

4) 660 (linear feet) x 4 (sides) = 2,640 linear feet to enclose 10 Acres.

## What happens when we increase the length of wire?

when you have longer length of wire, the current has to travel more distance, more the distance higher the number of obstacles it faces through its path. Therefore resistance increases with the length. When cross sectional area increases the space of the elctrons to travel increases(simply explained).

## How do you calculate the length of a wire?

Multiply the current figure by the diameter of the wire; for example, if the diameter of the wire is 1.5 inches, this figure would be multiplied by 1.5. The final figure should give the length of the wire.

## How do you calculate the length of a wire in Autocad?

To Calculate Wire Sizes Using the Circuit ManagerIn the Electrical workspace, select a wire and click Wire tab Circuits panel Circuit Manager drop-down Circuit Manager.On the right pane of the Circuit Manager, select the circuit (or circuits) to check. … Click (Calculate Wires).In the Calculate Wire Sizes dialog box, specify a resizing option: … Click OK.

## How do you calculate copper wire length?

Resistance of a wire in Ω < br > R = ρL/A < br > ρ is resistivity of the material in Ω-m < br > L is length in metre < br > A is transversal area in m² < br > A = πr² , r is radius of wire in m < br > resistivity Cu 17.2e-9 Ω-m < br > < br > there exists the formula , plug in the number .

## How many meters are in a coil of wire?

Toran 1.5 sq mm wire 90 meter coil (Green)

## How long is a roll of wire?

100m100m/roll or can be made as your request.

## Does length of wire affect current?

As the length increases, resistance increases, as a result current decreases. Length of wire definitely have effect on current and voltage.. Resistance is directly proportional to length. As the length increases, resistance increases, as a result current decreases.

## How do you calculate roll length?

Measure the diameter of the paper roll and the center hole using a tape measure. Write down the measurements. Use the caliper to measure and write down the thickness of the sheet of paper that is rolled. Multiply the roll of the diameter by 3.14159.

## Do wires add or reduce voltage?

Inevitably, if a current is flowing any wire has resistance and causes a voltsdrop. … But if the resistance of the splice is very small, then the reduction of voltage at the load will also be very small, and usually negligible.
