What is mass density of wire?
The volume of the wire is given by, V=πr2L. Thus density of the wire, ρ=πr2Lm
What is the formula of volume of wire?
Given: L = 21.7 cm and R = 0.46mm = 0.046 cm. Hence, the volume of wire = πr2l cubic units.
What is the area of wire?
The cross-sectional area of the wire is the area of a circle of radius r: A=πr2=π(d2)2, where d is the diameter of the wire.
What is the density of metal?
Density of Metals
| Material | Density (ρ) kg/m3 |
|---|---|
| Aluminum | 2,705 |
| Brass | 8,587 |
| Cast Iron | 7300 |
| Copper | 8,944 |
How do you calculate the density of a wire?
If you have a round wire you can calculate the volume if you know the radius and length (v=pi · sqr(r) · l) if you also have the weight (m) you get the density by dividing the weight by the volume. The density is ρ=m/v = m / (pi · sqr(r) · l) l is the length of the wire in meters.
Which is the correct formula for power density?
Given: P t = 100 watts G t = 10 (dimensionless ratio) R = 100 ft. This equation produces power density in watts per square range unit. For safety (radiation hazard) and EMI calculations, power density is usually expressed in milliwatts per square cm.
How is the density of a unit cell calculated?
Density of a unit cell is given as the ratio of mass and volume of unit cell. The mass of a unit cell is equal to the product of number of atoms in a unit cell and the mass of each atom in unit cell.
How to calculate density of a primitive cell?
Primitive unit cell: In a primitive unit cell, number of atoms in a unit cell, z is equal to one. Hence density is given as: Density of unit cell = ( frac {1~×~M }{a^3~×~N_A} ) Body-centered cubic unit cell: In body-centered cubic unit cell, number of atoms in a unit cell, z is equal to two.
