What area can a governor of a prison enclose in a circular compound if he has 100m of wire fencing?
C = 2πr = 100 mr = 100/(2π) = 50/πA = πr^2 = π(50/π)^2 = 2500/π m^3 ≈ 795.775 m^3
How do you calculate the area of the multi strand wire?
To calculate the area of a multi-strand wire you use the formula D = square root of (4S divided by pi), where S equals the number of strands times the area of one strand.
A wire extends from the top of a building to the ground 90 feet away from the building. The wire creates an angle of elevation of 22 and ordm with the ground. How long is the wire Round to the nearest?
Length of line: 90/cos(22) = 97 feet rounded to nearest the foot
What geometric figure suggested by a telephone wire?
SpheresQuadrilateral
What is 16 mesh?
16 is probably wire guage.
Is copper wire measured in circular mills?
Yes, copper wire can be measured in circular mils, which is a unit of area used in the electrical industry to specify the cross-sectional area of a wire. One circular mil is equal to the area of a circle with a diameter of one mil (1/1000 inch).
A conductor that is described as a 750 MCM wire has an area of what?
A 750 MCM wire has a cross-sectional area of approximately 500,000 circular mils.
Circular mils for 12 awg solid wire?
The cross-sectional area of a 12 AWG solid wire is approximately 6530 circular mils. Circular mils are commonly used to measure the cross-sectional area of wires and cables in electrical engineering.
A conductor thats described as a 750 mcm wire has an area of?
750,000 circular mils. A wire that is 1 mil (.001 inches) in diamter is defined to have an area of 1 circular mil. The area in circular mils = (diameter in mils) ^ 2. To convert this to area in square inches, multiply 750,000 * pi / 4,000,000 = 0.589 sq in.
What does 250kcmil AWG mean?
It is a wire size, the equivalent cross sectional area in thousands of circular mils. e.g. 500 MCM or kcmil = 500,000 circular mils. The circular mil is a unit of area used especially when denoting the cross-sectional size of a wire. It is the equivalent area of a circle whose diameter is 0.001 (10-3) inch. AWG stands for American Wire Guage.
Why are wires cylindrical?
It's easy to draw wire through a cylindrical die to make it. That and the fact that current that flows through the wire is depended on the wire cross section area, the circular shape is the maximized area for a given amount of material; therefore, a cylindrical wire is much more efficient.
Write a formula used to find circular mil area?
The ddiameter of No. 14 wire is 64 mils. What is its area in CM and in SM?
How do you calculate mils to circular mils?
1 circular mil = 1 mil x 1 mil a=d2 so if a wire has a diameter of 80 mils, it has an area of 6400 circular mils.
What is cma range when concerning electricity?
CMA (Circular Mil Area) is a unit used to measure the cross-sectional area of a wire. In the context of electricity, CMA range is the range of wire sizes expressed in circular mils that is commonly used for various applications, such as power transmission, wiring, and electrical installations. This range typically varies from a few thousand circular mils to several million circular mils.
Calculate cross sectional area of wire?
If the wire has a circular cross-section - the usual case - use the formula for the circle: pi x radius squared.
What is the cross sectional area of a wire?
If you slice a wire cleanly and then look at the cut end, you see a little circle at the end. The area of that circle is the "cross-sectional area" of the wire. The larger that area is, the lower the DC resistance of the wire is.
How do you work out the cross-sectional area of a wire?
Imagine the wire is straight, now cut through at right angle to the centre line, the exposed surface is the cross sectional area, on a round wire it = pi * radius2 (area of a circle)
