# How do you calculate the length of an Aluminium coil?

## How do you calculate the length of an Aluminium coil?

To obtain the coil length we have to divide the result by the section of the coil determined by coil width and thickness. The coefficient 1000 is used to compensate the dimensions in [mm] with the length in [m]. For example, a coil with OD = 1600mm, ID = 508mm and T = 0,6mm results in a length of 3010 meters.

### How do you calculate the resistance of aluminum wire?

CALCULATION OF CABLE RESISTANCE

- Hence R = 22.5/10 = 2.25 Ohms per km.
- Length of conductor = 500m =500/1000 = 0.5km.
- Therefore resistance of copper conductor = 2.25 x 0.5 =1.125 Ohms. Similarly for Aluminium,
- R = 36/S(c.s.a)
- Again S = 10mmsq.
- Hence R = 36/10 = 3.6 Ohms per km.
- Length of conductor = 0.5km.

#### How do I calculate coil wire length?

To calculate spring wire length per coil, you must subtract the wire diameter from the outer diameter in order to get mean diameter. Once you have calculated mean diameter, multiply it by pi (3.14); this will give you the length of wire per coil.

**How do you calculate coil turns?**

If you know the number of turns in the secondary coil and primary and secondary voltages. You can find out the number of turns in the primary using this formula: Np/Ns = Vp/Vs.

**How do you calculate the diameter of a coil?**

Wire diameter d is calculated using equations 5.3 and 5.5. Finally we obtain the dimensions of the spring: 10 active coils with wire diameter of 1.0 mm and mean coil diameter of 8 mm….Design procedure.

Wire diameter | 1.0 mm |
---|---|

Mean coil diameter | 8.0 mm |

Total coils | 12 |

Active coils | 10 |

Free length | 31.8 mm |

## How do you calculate roll length from diameter?

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.

### What is the resistance of Aluminium wire?

Cross Sectional Area (mm2) | Resistance (ohm/km) | |
---|---|---|

Copper | Aluminum | |

0.75 | 23 | 35.3 |

1.0 | 17.2 | 26.5 |

1.5 | 11.5 | 17.7 |

#### What is the resistance of aluminum wire?

Resistivity and Temperature Coefficient at 20 C

Material | Resistivity ρ (ohm m) | Conductivity σ x 107 /Ωm |
---|---|---|

Silver | 1.59 | 6.29 |

Copper | 1.68 | 5.95 |

Copper, annealed | 1.72 | 5.81 |

Aluminum | 2.65 | 3.77 |

**How do you measure copper wire length?**

Since copper has a known resistance value, the length of a spool of wire can be estimated simply by measuring its resistance value.

**What is the length of one coil wire?**

1 Coil – 90 mtr or 295.29 Feet.

## How do you calculate the number of Turns in a solenoid coil?

And we find that the number of turns in a solenoid is equal to its length times the magnetic field strength at its center divided by 𝜇 naught times the current in the solenoid 𝐼.

### What is coil turn ratio?

A 100:1 turns ratio (typical of many coils on the market) means there are 100 secondary turn windings to every one primary turn. With a 100:1 turns ratio and, for example, an initial 250-volt current-interruption spike, in theory there would be a spark output of 25,000 volts (assuming no losses to resistance).
