What percentage of voltage loss occurs in a coated No 18 stranded copper wire carrying 3A of current and running 228 feet from a 115-volt source to a receptacle?
To calculate the voltage loss in a No. 18 stranded copper wire carrying 3A over a distance of 228 feet, you can use the formula: Voltage Loss (V) = (2 * Length * Current * Resistance per unit length). The resistance of No. 18 copper wire is approximately 6.385 ohms per 1,000 feet. For 228 feet, the resistance would be about 1.46 ohms, resulting in a voltage drop of around 4.38 volts. This represents a voltage loss of approximately 3.81% of the 115-volt source.
How calculate weight per meter of 45x45x5 angle?
To calculate the weight per meter of a 45x45x5 mm angle, you first determine the volume of the angle. The formula for the volume can be approximated as the cross-sectional area multiplied by the length. The cross-sectional area of the angle can be calculated by considering the two legs and the thickness, and then multiplying by the length (1 meter). Finally, multiply the volume by the density of the material (typically for steel, it's around 7850 kg/m³) to get the weight per meter.
Thermal coefficient of Copper?
Copper has a CTE of 16.6 parts per million/degree C (16.6E-6/C)
How do you calculate 3X120sq.mm PILC cable capacitance?
To calculate the capacitance of a 3X120 sq.mm PILC (Paper Insulated Lead Covered) cable, you can use the formula for the capacitance per unit length of a three-core cable, which is approximately ( C = \frac{2\pi \epsilon}{\ln(\frac{D}{r})} ), where ( \epsilon ) is the permittivity of the insulation material, ( D ) is the distance between the conductors, and ( r ) is the radius of the conductor. The total capacitance can then be derived by multiplying the capacitance per unit length by the length of the cable. Specific values for ( \epsilon ), ( D ), and ( r ) should be obtained based on the cable's construction and insulation type.
Formula to calculate weight of MS pipes per meter length?
The formula to calculate the weight of MS (Mild Steel) pipes per meter length is as follows: Weight per meter = (outer diameter - thickness) * thickness * 0.0246615 * 2.76, where the outer diameter and thickness are in millimeters. This formula takes into account the density of mild steel (7.85 g/cm³) and the conversion factor to get the weight in kilograms per meter. It is important to ensure that the units are consistent throughout the calculation to obtain an accurate result.
How do calculate weight of 50mm6mm copper strip per meter?
You convert everything to a common unit, for example meters, multiply length x width x height to get the volume, then multiply this volume by the density of copper, which you can easily look up. - Actually this will give you the mass, not the weight. If you really want the weight, you can multiply the mass by Earth's gravity - about 9.8. Alternately, you can weigh a sample.
How do you calculate resistivity of copper wire?
(rho) or resistivity of a "wire" is calculated using this formule:rho = Resistance x Area / length of materialthe resistivity of copper is 1.7 x 10 -8 ohm/mResistivity is measured in ohm metres, NOT ohms per metre!
What is the frequency formula used to calculate the resonance frequency of a tuning fork?
The frequency formula used to calculate the resonance frequency of a tuning fork is f (1/2) (Tension / (Mass per unit length Length)), where f is the resonance frequency, Tension is the tension in the tuning fork, Mass per unit length is the mass per unit length of the tuning fork, and Length is the length of the tuning fork.
What is the coefficient of expansion of copper pipe?
The coefficient of linear expansion for copper is around 16.5 x 10^-6 per degree Celsius. This means that for every degree Celsius increase in temperature, a one-meter length of copper pipe will expand by 16.5 micrometers in length.
How many atoms are in a 1cm of copper wire and who calculate this?
The number of atoms in a 1cm length of copper wire can be calculated using Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. The molar mass of copper is around 63.55 g/mol, so you would find the mass of copper in 1 cm of wire and then convert that to moles to determine the number of atoms.
How much is1.5 sqmm per unit resistance of a cable?
The resistance of a 1.5 sqmm cable depends on its material (usually copper or aluminum) and its length. For copper, the typical resistance is about 12.1 ohms per kilometer, while for aluminum, it’s around 19.5 ohms per kilometer. To find the resistance per unit length, you would divide these values by 1000 to get ohms per meter. Thus, the resistance of a 1.5 sqmm copper cable is approximately 0.0121 ohms/meter.
Formula to calculate weight of MS flanges per meter length?
200*75*7
Can you calculate the mass of a single copper atom?
The mass of a single copper atom is approximately 1.055 x 10^-25 kilograms. This value is determined by the atomic mass of copper (63.55 grams per mole) and Avogadro's number.
How much does copper cost per linear meter?
The cost of copper per linear meter can vary depending on market conditions and the type of copper being purchased. As of current market data, the price of copper can range between $5 to $10 per linear meter. It's advisable to check with local suppliers or online sources for the most up-to-date pricing information.
What is the formula to calculate the weight of rectangular copper?
Calculate the volume = length * breadth * thickness, where these are measured in centimetres. Multiply by the density = 8.96 grams per cubic centimetre to obtain the mass in grams. Divide by 1000 to get the mass in kilograms. Finally, multiply by 9.8, the acceleration due to gravity. The answer is the weight, in Newtons.
What is the weight of 400 mcm copper wire per foot?
